Plaintiffs appeal from the trial court's dismissal of their petition. We reverse and remand.
In their petition, plaintiffs allege they are representatives of a class who have worked or will work on property adjacent to a radiopharmaceutical processing plant operated by defendant, Mallinckrodt, Inc. (Mallinckrodt). Alleging injuries to their physical and mental health from exposure to radioactive emissions released by the plant, plaintiffs seek damages from Mallinckrodt based on three theories of common law tort: negligence, assault and battery and strict liability for "ultrahazardous activities." In the trial court, Mallinckrodt filed a motion to dismiss, arguing that plaintiffs' action was barred (1) by the federal preemption doctrine, (2) by the political question doctrine and (3) by the action being based upon mere speculative possibilities of future harm. The trial court dismissed plaintiffs' petition on two grounds: the court lacked subject matter jurisdiction and the petition failed to state a claim upon which relief could be granted.
We disagree with the trial court. The court does have subject matter jurisdiction, and plaintiffs' petition, although not artfully drawn, does state a claim upon which relief can be granted.
The issues before us are the same three issues which were before the trial court. We address them in order.

FEDERAL PREEMPTION
The doctrine of federal preemption springs from the Supremacy Clause of the United States Constitution, U.S. Const., Art. VI, cl. 2. E.g., Fidelity Fed. Savings & Loan Ass'n v. de la Cuesta, 458 U.S. 141, 152, 102 S.Ct. 3014, 3022, 73 L.Ed.2d 664 (1982). The question of whether federal law preempts state action is "`largely one of statutory construction'" and, therefore, cannot be resolved by general formulas. Cipollone v. Liggett Group, Inc., 593 F.Supp. 1146, 1150 (D.N.J.1984).[1] Certain principles, however, have been clearly established. First, federal law may expressly preempt state law, Northern States Power Co. v. Minnesota, 447 F.2d 1143, 1145-46 (8th Cir.1971), aff'd, 405 U.S. 1035, 92 S.Ct. 1307, 31 L.Ed.2d 576 (1972), or, state law in a given area may be preempted by Congress' implied intent to occupy that area. E.g., Fidelity Fed., 458 U.S. at 153, 102 S.Ct. at 3022; Rice v. Santa Fe Elevator Corp., 331 U.S. 218, 230, 67 S.Ct. 1146, 1152, 91 L.Ed. 1447 (1947). Even if Congress has not entirely displaced state regulation in a given area, state law may still be preempted to the "extent it actually conflicts with federal law, that is, when it is impossible to comply with both state and federal law ..., or where the state law stands as an obstacle to the accomplishment of the full purposes and objectives of Congress...." Silkwood v. Kerr-McGee Corp., 464 U.S. 238, 104 S.Ct. 615, 621, 78 L.Ed.2d 443 (1984).
Congressional intent pertaining to nuclear energy surfaces in the Atomic Energy Act and its amendments. Until 1954, the development of nuclear energy was a federal monopoly. See Atomic Energy Act of 1946, Pub.L. No. 79-585, 60 Stat. 755. With the enactment of the Atomic Energy Act of 1954, ch. 1073, 68 Stat. 919, codified as amended, 42 U.S.C. §§ 2011-2284 (1982), private industry was encouraged to take part in the development and utilization of nuclear energy for peaceful purposes. The federal government, however, retained extensive control over this development by means of a licensing scheme administered by the Atomic Energy Commission, AEC, the predecessor of the present Nuclear Regulatory Commission, NRC.
In 1959, Congress amended the Atomic Energy Act and authorized the NRC to turn over some regulatory authority to those states that adopted a suitable regulatory program, see 42 U.S.C. § 2021, but *858 states were still precluded from regulating the safety aspects of nuclear development, see 42 U.S.C. § 2021(k). See also Pacific Gas & Electric Co. v. State Energy Resources Conservation & Development Comm., 461 U.S. 190, 205, 103 S.Ct. 1713, 1722, 75 L.Ed.2d 752 (1983); Northern States Power Co., 447 F.2d at 1153-54; State ex rel. Utility Consumers Council v. Public Service Comm., 562 S.W.2d 688, 698 (Mo.App.), cert. denied, 439 U.S. 866, 99 S.Ct. 192, 58 L.Ed.2d 177 (1978).
Congress also amended the Atomic Energy Act in 1957 by passing the Price-Anderson Act, Pub.L. No. 85-256, 71 Stat. 576 (1957), to encourage private enterprise to participate in the nuclear industry. Companies contemplating entry into the field had expressed considerable concern over the possibility of a nuclear accident with concomitant bankrupting liability. See Silkwood v. Kerr-McGee Corp., 104 S.Ct. at 623; S.Rep. No. 296, reprinted in 1957 U.S.Code Cong. & Ad.News 1803, 1816. Through financial protection and indemnification provisions, the Price-Anderson Act attempted to alleviate this concern by shielding the nuclear industry while safe guarding the public financially. As a result, the Act requires certain licensees to purchase private insurance to cover liability claims, 42 U.S.C. § 2210(a), (b), provides government indemnity for those licensees, 42 U.S.C. § 2210(c), (d), and establishes maximum limits on liability for nuclear incidents,[2] 42 U.S.C. § 2210(e). See also Silkwood v. Kerr-McGee Corp., 667 F.2d 908, 921 (10th Cir.1981). Then, in response to a concern that many states would not apply strict liability to radiation injuries, Congress again amended the Act in 1966 and required all indemnified nuclear facilities to waive certain legal defenses such as contributory negligence and governmental immunity in the event of an extraordinary nuclear occurrence.[3]See 42 U.S.C. § 2210(n).[4]
The enactment of the Price-Anderson Act and its subsequent amendments triggered an extensive legislative history concerning the relationship between federal statutes pertaining to the nuclear industry and state tort law. No less an authority than the United States Supreme Court has interpreted this history and defined this relationship for us. See, e.g., Silkwood v. Kerr-McGee Corp., 464 U.S. 238, 104 S.Ct. 615, 78 L.Ed.2d 443 (1984); Pacific Gas & Electric Co. v. State Energy Resources Conservation & Development Comm'n, 461 U.S. 190, 103 S.Ct. 1713, 75 L.Ed.2d 752 (1983).
The Supreme Court has declared, in essence, that states are precluded from regulating the safety aspects of nuclear development and of hazardous nuclear materials. Pacific Gas & Electric Co., 461 U.S. at 205, 103 S.Ct. at 1722; Silkwood, 104 S.Ct. at 622. This prohibition is premised on Congress' belief that the NRC is more qualified than the individual states to determine what type of safety standards should be enacted in this complex area. Silkwood, 104 S.Ct. at 622. Acknowledging Congress' concern over the state's inability to formulate effective safety standards, the Court in Silkwood, nonetheless, found "ample evidence" in the legislative history that Congress had no intention of forbidding states from providing tort remedies for injuries caused by nuclear radiation. Id. at 623. For example, the Court quoted *859 from Senate Report No. 296 which explains the Price-Anderson Act does not interfere with state tort law until there is a likelihood that damages would exceed the amount of financial responsibility required together with the amount of federal indemnity. Up to this threshold point, the rights of injured parties are established and defined by state law. Id. at 623. See also S.Rep. No. 296, 1957 U.S.Code Cong. & Ad.News 1803, 1810.[5]
As a result, "[s]tate law remedies, in whatever form they might take, [are] available to those injured by nuclear incidents." Silkwood, 104 S.Ct. at 625. Consequently, the mere fact the federal government has occupied the field of safety does not foreclose state remedies for radiation injuries. Rather, the test for determining preemption in the nuclear energy field is:
"[1] whether there is an irreconcilable conflict between the federal and state standards or [2] whether the imposition of a state standard in a damages action would frustrate the objectives of the federal law." Silkwood, 104 S.Ct. at 626.

THE RECORD
Mallinckrodt contends plaintiffs' action irreconcilably conflicts with federal standards and also frustrates federal objectives. A fact essential to this contention is Mallinckrodt's compliance with federal statutes and regulations. This fact, however, has neither been pleaded nor proved.
Plaintiffs' have not alleged Mallinckrodt's compliance with federal statutes or regulations, nor is this fact implicit in any of plaintiffs' claims. Moreover, Mallinckrodt has not filed an answer to plaintiffs' petition, nor has it filed a motion for summary judgment based upon facts established by affidavit or discovery. Mallinckrodt has simply filed a motion to dismiss plaintiffs' petition.
Mallinckrodt, in effect, is seeking an advisory opinion before pleading or proving compliance. Plaintiffs, nevertheless, address Mallinckrodt's arguments as if Mallinckrodt's compliance existed. We address the arguments as presented, rather than avoiding the preemption issues on a procedural defect.[6]

IRRECONCILABLE CONFLICT
Permitting plaintiffs' petition to state a claim for relief under Missouri law, Mallinckrodt argues, would create an irreconcilable conflict between Missouri and federal standards. Mallinckrodt contends that subjecting it to state tort liability effectively establishes a "zero-release standard." More specifically, Mallinckrodt argues, that if a permissible release is to be determined by a jury "after the fact on an ad hoc basis," a federal licensee, like Mallinckrodt, "could assure avoidance of liability only by a zero release of emissions." This state imposed standard, Mallinckrodt reasons, irreconcilably conflicts with federal standards.
Mallinckrodt's logic is questionable. More important, its conclusion is not persuasive. As other manufacturers, producers and operators functioning in a regulated field, Mallinckrodt is not guaranteed absolute insulation from the consequences of its acts through compliance with federal regulation. See McKay v. United States, *860 703 F.2d 464, 470 (10th Cir.1983) and Silkwood v. Kerr-McGee Corp., 485 F.Supp. 566, 578-79 (W.D.Okla.1979) and cases cited therein. Thus, the issue here is not whether Mallinckrodt will be assured of freedom from liability. Rather, the issue is whether there is an irreconcilable conflict between our state standards and federal standards; an issue which, in turn, is answered by whether it is impossible for Mallinckrodt to comply with both federal standards and those standards implicitly reflected in plaintiffs' petition. Silkwood, 104 S.Ct. at 626.
As noted, we are at the pleading stage with only plaintiffs' petition before us. Mallinckrodt has not shown our state standards to be more stringent than federal standards, nor has it shown our state standards to be theoretically or practically impossible to meet, if our state standards are in fact more stringent. Moreover, even if Mallinckrodt cannot reduce its radiation emissions below the federal standards, Missouri can decide that, as between Mallinckrodt and plaintiffs, Mallinckrodt ought to bear the costs of compensating those injuries that could have been prevented with a theoretical emission rate lower than the rate approved by the NRC. See Ferebee v. Chevron Chemical Co., 736 F.2d 1529, 1540-41 (D.C.Cir.), cert. denied, ___ U.S. ___, 105 S.Ct. 545, 83 L.Ed.2d 432 (1984). On the present record, payment of damages and compliance with federal standards are clearly possible. Mallinckrodt can continue to meet federal standards, and, if found wanting by state standards, simply pay the piper.
Arguably, imposing damages for state torts committed by parties operating under federal standards has a possible state regulatory effect on the federal standards. A possible regulatory effect on federal standards by state tort actions, however, has long been accepted. See, e.g., Cipollone, 593 F.Supp. at 1155-56. Congress' acceptance of this possibility in the nuclear energy field was specifically noted by the Supreme Court in Silkwood v. Kerr-McGee, 104 S.Ct. at 625:
No doubt there is tension between the conclusion that safety regulation is the exclusive concern of the federal law and the conclusion that a state may nevertheless award damages based on its own law of liability. But as we understand what was done over the years in the legislation concerning nuclear energy, Congress intended to stand by both concepts and to tolerate whatever tension there was between them. We can do no less. It may be that the award of damages based on the state law of negligence or strict liability is regulatory in the sense that a nuclear plant will be threatened with damages liability if it does not conform to state standards, but that regulatory consequence was something that Congress was quite willing to accept.
In short, common law liability does not impose requirements on Mallinckrodt; rather, it allows Mallinckrodt to choose between risking liability by not changing its behavior or attempting to negate the risk by lowering its emission rates. Cipollone, 593 F.Supp. at 1167. This reasoning may appear to be disingenuous and smack of sophistry; if so, the charge must be made against the entire judiciary for the reasoning has been continually used to justify the imposition of state tort liability as a "complement to" federal standards. See Silkwood, 104 S.Ct. at 629-30 (Blackmun, J., dissenting); Ferebee, 736 F.2d at 1541; Cipollone, 593 F.Supp. at 1167, and cases collected therein.

FRUSTRATION OF FEDERAL OBJECTIVES
Mallinckrodt also argues that to permit recovery here would frustrate the objectives of federal law. The purpose of the Atomic Energy Act, Mallinckrodt points out, is to promote private nuclear development. If federal licensees like Mallinckrodt are subjected to claims even if in compliance with federal standards, then, Mallinckrodt reasons, the purpose of the Act would be frustrated by permitting state *861 law to regulate federal licensees and discourage private industry.
As just noted, the Supreme Court addressed this specific issue in Silkwood v. Kerr-McGee. Tort recovery to injured plaintiffs may create a tension between state law and federal law, but Congress was willing to accept this consequence. Silkwood, 104 S.Ct. at 625. The fact that some plaintiffs may be successful in recovering compensation from Mallinckrodt for injuries suffered does not mean that the state is setting its own emission levels. Silkwood, 104 S.Ct. at 626.
Moreover, if plaintiffs' recovery in tort merely inconveniences Mallinckrodt or makes its operation more costly, there is no frustration of federal policy or purpose. See, e.g., Marshall v. Consumers Power Co., 65 Mich.App. 237, 237 N.W.2d 266, 281-82 (1975). State tort actions may frustrate federal objectives if the federal regulatory statutes have as an objective the affirmative subsidization of the regulated industry and if the statutes, explicitly or implicitly, command states to accept the use of the regulated product. Ferebee, 736 F.2d at 1542-43. The Atomic Energy Act, however, does not subsidize the nuclear industry. One of the purposes of the Atomic Energy Act may be to promote the peaceful development of nuclear energy, but the Act does not subsidize the nuclear industry to such an extent that states are commanded to use or accept the use of nuclear energy. See, e.g., Pacific Gas, 461 U.S. at 205, 103 S.Ct. at 1722. States do have some control over the extent of use of nuclear materials within their boundaries as well as determining where and whether such use will occur. See, e.g., State ex rel. Utility Consumers Council, 562 S.W.2d at 698. They are not always required to tolerate actions permissible under federal law, see, e.g., Pacific Gas, 461 U.S. at 216, 222-23, 103 S.Ct. at 1728, 1731-32; Ferebee, 736 F.2d at 1543, and this is one such area.
Furthermore, radiation emission standards lower than federal emission standards are consistent with the federal aim of achieving radiation emissions as low as reasonably possible. See 10 C.F.R. § 20.1(c). The NRC has established emission standards designed to protect the public and, at the same time, allow for further development of nuclear energy using current technology. 10 C.F.R. § 20.1(c), 10 C.F.R. § 20.105-.106; 42 U.S.C. § 2201(b). These standards reflect an administrative decisionan administrative balancing of overall societal risks against societal benefits. Silkwood, 485 F.Supp. at 581-82; Crowther v. Seaborg, 312 F.Supp. 1205, 1231 (D.Colo.1970); Keyes & Howarth, Approaches to Liability for Remote Causes: The Low-Level Radiation Example, 56 Iowa L.Rev. 531, 541, 568 (1971). Emission standards adequate for administrative purposes in meeting governmental goals, however, are not necessarily adequate for purposes of state tort law encompassing broader compensatory goals. These administrative emission standards are not absolute safety levels below which no injury can occur. Silkwood, 485 F.Supp. at 579-81; Keyes & Howarth, supra, at 545. As a result, insofar as state law is concerned, they are merely guidelines.
This conclusion is reflected in the prefatory language of 10 C.F.R. § 20. In various subsections, § 20 sets out the emission standards for NRC licensees. Preceding these subsections, the Purpose Clause of § 20 states:
"In accordance with recommendations of the Federal Radiation Council, ... [licensees] should, in addition to complying with the requirements set forth in this part, make every reasonable effort to maintain radiation exposures, ... as low as is reasonably achievable." 10 C.F.R. § 20.1(c).
This language clearly implies the federal standards are, at best, guidelines to state tort law. "In addition to complying with" the federal standards, licensees are requested to make every reasonable effort to achieve emissions as low as is reasonably achievable. Compliance with federal standards is mandatory; the request to achieve emission rates lower than these standards, *862 however, implicitly acknowledges these lower rates may, in fact, be achieved. Moreover, the determination of the reasonableness of the effort to achieve these lower rates is not exclusively arrogated by the NRC. Sensibly, this implies state tort law can determine whether reasonable efforts have been made, and, thus, complement the NRC standards. This implication is reinforced by the industrial and commercial use of nuclear energy still being at the cutting edge of science. Scientific data affecting reasonable emission standards change often and rapidly. See Silkwood, 485 F.Supp. at 581; Keyes & Howarth, supra, at 540. Thus, even though NRC emission standards may be based upon the best scientific data available at the time they are promulgated, these standards necessarily lag behind the change in scientific data. Keyes & Howarth, supra, at 540. To accept Mallinckrodt's reasoning would leave parties injured by radioactive emissions without recourse when science or technology has improved to permit levels of emissions lower than those currently established by the NRC.
This was not Congress' intent. States may be preempted from setting their own emission standards, but they are not preempted from compensating injured citizens. See Silkwood, 104 S.Ct. at 625-26. "Congress ... disclaimed any interest in promoting the development and utilization of atomic energy by means that fail to provide adequate remedies for those who are injured by exposure to hazardous nuclear materials." Silkwood, 104 S.Ct. at 626.

INCIDENT/ACCIDENT
Mallinckrodt also argues that if any state tort claims survive preemption, the only permissible ones are those arising out of a "nuclear incident." Relying on the facts of Silkwood, selected language from that case as well as selected passages from the legislative history of the Price-Anderson Act, Mallinckrodt defines "nuclear incident" as "an accidental release of radiation in excess of federal limits." Mallinckrodt then argues releases in compliance with federal regulations cannot constitute accidents or "nuclear incidents" and, therefore, claims, like plaintiffs, seeking recovery for alleged injuries resulting from "planned, federally permissible releases" must be preempted. We read Silkwood as well as the legislative history differently.
Mallinckrodt views Silkwood as dealing with three separate incidents of contamination of Karen Silkwood away from Kerr-McGee's plant. These three events are in turn viewed as constituting something out of the ordinarya "nuclear incident." Mallinckrodt also seizes on "nuclear incident" being used interchangeably with "nuclear accident" by various courts, including the Supreme Court in Silkwood, to show the latter term necessarily defines the former. See, e.g., Silkwood, 104 S.Ct. at 623, 625.
Mallinckrodt's logic is flawed. If "nuclear incident" is a term of art, its definition is found in 42 U.S.C. § 2014(q), which, as noted, defines "nuclear incident" to mean "any occurrence ... causing ... bodily injury, sickness, disease, or death, ...." The courts' use of "incident" interchangeably with "accident" to describe or refer to the particular facts before them does not circumscribe the broad generic definition. Courts also use the term "hazard" and "occurrence" interchangeably with the term "incident." See, e.g., Silkwood, 104 S.Ct. at 624, 626. Obviously, the generic term "occurrence" includes the more limited defined term "accident." Applying Mallinckrodt's reasoning to these interchanged references means the term "incident" could also be equated with "hazard" or "occurrence." No sensible argument can be made that any emission or exposure is not an occurrence or does not entail some hazard.
This same argument was summarily dealt with in Van Dissel v. Jersey Central Power & Light Co., 194 N.J.Super. 108, 476 A.2d 310, cert. denied, 99 N.J. 186, 491 A.2d 690 (1984). Upon remand by the United States Supreme Court for further consideration in light of Silkwood v. Kerr-McGee Corp., 464 U.S. 238, 104 S.Ct. 615, 78 L.Ed.2d 443 (1984), the New Jersey Superior *863 Court found no preemption of claims for property damage resulting from the normal operation of a nearby nuclear power reactor plant. In reaching its decision, the New Jersey Court concluded, as we conclude here, that compensable injuries do not have to be caused by "nuclear accidents." 476 A.2d at 316. See also McKay v. United States, 703 F.2d at 465.
We have also carefully read the selections of congressional debates and reports cited by Mallinckrodt in support of its position. We remain unpersuaded. The examples of "typical" nuclear incidents Mallinckrodt selects from the legislative history are examples of incidents but are not necessarily typical. One of Congress' concerns in enacting the Price-Anderson Act and its subsequent amendments was to protect the public by assuring the availability of funds for claims arising out of major nuclear incidents. See, e.g., S.Rep. 454, 94th Cong., 1st Sess. (1975), U.S.Code Cong. & Admin. News 1975, p. 2251; H.R.Rep. No. 2043, 89th Cong., 2d Sess. (1966). Most, if not all, of Mallinckrodt's cited examples address this concern and, thus, are examples of major or catastrophic incidents.[7] This does not mean that emissions or exposures less than federal limits are preempted or are not included under the Price-Anderson indemnification system. Standard insurance was assumed to cover minor incidents, and, for these, the nuclear industry would not need federal assistance. See, e.g., H.R. Rep. No. 2043, 89th Cong., 2d Sess. 11 (1966). Consequently, in the hearings, reports and debates cited by Mallinckrodt, the precise definition of a nuclear incident, especially in relation to minor incidents, was not a concern.
If plaintiffs' claims must be confined to "nuclear incidents" as defined in federal statutes, plaintiffs' claims are properly pleaded. The term nuclear incident means:
"any occurrence, ... causing, ... bodily injury, sickness, disease, or death, or loss of or damage to property, or loss of use of property, arising out of or resulting from the radioactive, ... properties of source, special nuclear, or byproduct material...." 42 U.S.C. § 2014(q).
This definition is "designed to protect the public against any form of damage arising from the special dangerous properties of the materials used in the atomic energy program." S.Rep. No. 296, 1957 U.S.Code Cong. & Ad.News 1817. Moreover, an incident does not necessarily have to occur within a short period of time, and steady exposure to radiation, perhaps, from an undetected leak of radioactive materials, can constitute an incident. Id. We also note 42 U.S.C. § 2014(q) itself does not require an accidental or unplanned release. See also McKay v. United States, 703 F.2d 464 (10th Cir.1983).
In summary, the legislative history of the Price-Anderson Act and its amendments, as well as case law, consistently reflect the underlying principle of interfering with state law to the minimum extent necessary. E.g., S.Rep. No. 1605, 1966 U.S.Code Cong. & Ad.News 3206. Consequently, the rights of a party injured by radiation are for the most part left to state law. S.Rep. No. 296, 1957 U.S.Code Cong. & Ad.News 1810. While we may be attracted by the logic of some of Mallinckrodt's arguments supporting preemption, our understanding of Silkwood is that its reach is greater and much more inclusive than the limits Mallinckrodt would place on it. We are constrained to follow not only the holding of Silkwood but also to follow our understanding of its teaching.

POLITICAL QUESTION DOCTRINE
The political question doctrine establishes a limitation on the authority of the judiciary to resolve issues, decidedly political in nature, that are properly left to *864 the legislature. If a case actually involves the resolution of a political question, the matter is immune from judicial review. There should, however, be no dismissal for nonjusticability on the basis of a political question's presence unless
"[p]rominent on the surface of any case held to involve a political question [there] is found a textually demonstrable constitutional commitment of the issue to a coordinate political department; or a lack of judicially discoverable and manageable standards for resolving it; or the impossibility of deciding without an initial policy determination of a kind clearly for nonjudicial discretion; or the impossibility of a court's undertaking independent resolution without expressing lack of the respect due coordinate branches of government; or an unusual need for unquestioning adherence to a political decision already made; or the potentiality of embarrassment from multifarious pronouncements by various departments on one question." Baker v. Carr, 369 U.S. 186, 217, 82 S.Ct. 691, 710, 7 L.Ed.2d 663 (1962).
The propriety of nuclear related activities is a political question properly committed to the legislative and executive branches of our government. Nonetheless, individual tort recoveries stemming from those activities normally are not precluded by the political question doctrine. McKay, 703 F.2d at 470. "If Congress had intended that some department or departments should have full and complete and exclusive authority in the area of obtaining redress for injuries, it certainly would have said so either in the legislative history or in the Act itself." Id. at 472.
Defendant relies on Crowther v. Seaborg, 312 F.Supp. 1205 (D.Colo.1970) to assert plaintiffs' claim was barred by the political question doctrine. Crowther is distinguishable, however. The plaintiffs in Crowther were seeking an injunction to stop testing involving nuclear detonations and a determination that the applicable radiation safety standards were inadequate. The court in Crowther rightly held that the extent and nature of government participation in the development of energy sources was a political question as was the establishment of radiation protection standards. 312 F.Supp. at 1231-32. Plaintiffs in this case, however, are not trying to establish standards that conflict with legislative determinations; they are seeking compensation for injuries. Nor does the allowing of recovery for those injuries which do occur mean the state is creating new standards; rather, the state is protecting its citizens by making defendant responsible for injuries arising from its activities as a cost of doing business.

FAILURE TO STATE A CLAIM
Plaintiffs plead their three theories of liability in three separate Counts: Count Inegligence, Count IIassault and battery, Count IIIstrict liability. Although stated somewhat differently in two of the three Counts, plaintiffs allege their injuries result from Mallinckrodt's radioactive emissions which have or will cause (1) "various health and physical illnesses" and "injury, damages to health, property and safety of plaintiffs," (2) "a drastic increase in the class of many physical illnesses," such as "lukemia, cancer and nervous disorders," and (3) "apprehension ... [because of] severe psychotic trauma" from the exposure and increased risk of illness.[8]
Focusing on these allegations of damages, Mallinckrodt argues that plaintiffs have failed to state a claim because they do not "specifically allege any particular individual has sustained an identifiable and detectable physical injury." We disagree.
Injury is an essential element of a tort based on negligence. E.g., Chubb *865 Group of Ins. Cos. v. C.F. Murphy & Assocs., Inc., 656 S.W.2d 766, 774 (Mo.App. 1983); See also W. Prosser, Law of Torts § 30, at 143 (4th ed. 1971). It also is an essential element of a tort based on strict liability. E.g., Restatement (Second) of Torts § 519 (1977). Thus, unless plaintiffs properly plead their injuries in their negligence and strict liability claims, they have failed to state a claim upon which relief can be granted.[9]See, e.g., Dix v. Motor Market, Inc., 540 S.W.2d 927, 932 (Mo.App. 1976).

PLAINTIFFS' PLEADED INJURIES
(1) "Various health and physical illness" and "Injury, damages to health, property and safety to plaintiffs"
Technical forms of pleading are no longer required. Rule 55.04. To plead a claim for relief, the pleader must simply allege a "plain statement of the facts showing [he] is entitled to relief...." Rule 55.05. Although the pleader need not allege evidentiary or operative facts, e.g., Scheibel v. Hillis, 531 S.W.2d 285, 290 (Mo. banc 1976), he must allege ultimate facts, id. at 290, and cannot rely on mere conclusions, e.g., Commercial Bank of St. Louis County v. James, 658 S.W.2d 17, 22 (Mo. banc 1983). These rules and their interpretations are much easier stated than applied. Many allegations simply do not fall within a precise definition of a fact. They are mixed statements of fact and conclusions. In Missouri, however, we still remain stuck in a semantic morass, attempting to differentiate fine and evanescent distinctions between evidentiary facts, ultimate facts and conclusions. See, e.g., Einhaus v. Ames Co., 547 S.W.2d 821, 825 (Mo.App.1976). To us, the distinction is really one between generality and particularity.
Admittedly, forceful argument can be made that plaintiffs' allegations of injury are vague and ambiguous. Mere vagueness, however, is not grounds for a motion to dismiss, e.g., Pillow v. Gen. American Life Ins. Co., 564 S.W.2d 276, 279 (Mo.App. 1978), and we prefer to dispose of a case on its merits instead of on the pleadings, see, e.g., Laclede Gas Co. v. Hampton Speedway Co., 520 S.W.2d 625, 631 (Mo.App. 1975). More important, a petition should be dismissed only if it appears the pleader can prove no set of facts in support of his claim for relief. E.g., Gaines v. Monsanto Co., 655 S.W.2d 568, 570 (Mo.App. 1983); Pillow, 564 S.W.2d at 279-80.
The narrow issue here is whether plaintiffs' allegations of "various health and physical" illnesses or "injury" generally are ultimate facts or conclusions. Rational application of our basic pleading principles can be used to classify plaintiffs' allegation of injuries either as ultimate facts or conclusions. Rather than torture logic to reach a preconceived result, we focus on whether Mallinckrodt knows what this action involves. We think it does. If plaintiffs were pleading in the federal courts, their allegations of injuries would withstand a motion to dismiss. Pearl v. Allied Corp., 566 F.Supp. 400, 403-04 (E.D. Penn.1983). Mallinckrodt is no less informed simply by being sued in our state courts. Admittedly, there are differences between the so-called "notice pleading" in the federal court and our code pleading. The only relevant difference here, however, would be that plaintiffs' allegations of injuries in the federal courts not only would withstand a motion to dismiss but also would withstand a motion to make more definite and certain, see, e.g., 2A Moore's Fed.Practice, §§ 12.08, 12.18 (2d ed. 1985), but, in our courts, these allegations would be and are subject to a motion to make more definite and certain.
Plaintiffs' pleadings are subject to a motion to make more definite and certain because they lack sufficient detail for Mallinckrodt to prepare a responsive pleading. Rule 55.27(d). Arguably, Mallinckrodt could answer by filing a general denial and *866 use discovery to gain information for trial. But an important element of plaintiffs' claims is a medically diagnosable injury or illness. A clear diagnosis is essential for identifying the precise cause of the injury and identifying Mallinckrodt as the culprit. Thus, although the injuries as pled withstand the motion to dismiss, they are subject to make more definite and certain. Rule 55.27(d).
(2) "A drastic increase in the class of many physical illnesses" such as "lukemia, cancer and nervous disorders."
In the pleaded injuries just discussed, plaintiffs' claim present physical injuries. The question there was whether the language used was precise enough to state a claim. In this claim of injury, plaintiffs allege future injuries. Sensibly read, plaintiffs allege the exposure to radiation has increased their risk as candidates for cancer. The question here is whether plaintiffs may recover on the theory that their increased risk of contracting cancer is a present injury.
In Missouri, no different than most other jurisdictions, future damages in a personal injury action are not compensable unless reasonably certain to occur. See, e.g., Hahn v. McDowell, 349 S.W.2d 479, 482 (Mo.App.1961). No Missouri Court, however, has been confronted with the precise issue here. Courts in other jurisdictions have. In resolving the issue, they quite logically determine whether the enhanced risk from exposure to a toxic substance, as pleaded or proved, is a reasonable certainty or can be considered a reasonable certainty. They find it is not. See, e.g., Morrissy v. Eli Lilly & Co., 76 Ill. App.3d 753, 32 Ill.Dec. 30, 37, 394 N.E.2d 1369, 1376 (1979); Ayers v. Township of Jackson, 189 N.J.Super. 561, 461 A.2d 184, 187 (Law Div.1983); Askey v. Occidental Chemical Corp., 102 A.D.2d 130, 477 N.Y. S.2d 242, 247 (1984). See also Laswell v. Brown, 683 F.2d 261, 269 (8th Cir.1982), cert. denied, 459 U.S. 1210, 103 S.Ct. 1205, 75 L.Ed.2d 446 (1983); Mink v. University of Chicago, 460 F.Supp. 713, 719 (N.D.Ill. 1978).
This resolution makes sense. Plaintiffs here, like the plaintiffs in the cited cases, base their claim on mathematical probabilities. Damages based on mere mathematical probabilities significantly undercompensate those who actually develop cancer and are a windfall to those who do not. No acceptable definition of justice would contemplate such a result. Consequently, this claim of injury is fatally defective.
(3) "Apprehension ... [because of] severe psychic trauma from the exposure and increased risk of illness."
We have paraphrased this pleading of injury.[10] As we understand it, plaintiffs seek to recover for emotional distress allegedly suffered by them as a result of being exposed to radiation, and plaintiffs seek compensation for this emotional distress without a showing of physical injury. In short, plaintiffs seek compensation for fear of cancercancerphobia.
Plaintiffs allege their emotional distress is a direct result of Mallinckrodt's tortious conduct. Plaintiffs no longer need to allege a contemporaneous physical injury to plead a tort action for emotional distress. See Bass v. Nooney Co., 646 S.W.2d 765, 772 (Mo. banc 1983); Young v. Stensrude, 664 S.W.2d 263, 265 (Mo.App. 1984). Plaintiffs need only to plead Mallinckrodt should have realized its conduct *867 involved an unreasonable risk of causing plaintiffs' emotional distress and the distress is medically diagnosable and medically significant. Bass v. Nooney, 646 S.W.2d at 772-73.
We have read plaintiffs' petition carefully, giving it the most liberal interpretation. Our pleading principles may abolish the technicalities of pleading. They do not abolish the need for clear thinking and clarity. Plaintiffs do plead a "psychic trauma," which is medically diagnosable and can be medically significant.[11] Plaintiffs, however, do not plead Mallinckrodt should have realized its alleged conduct involved an unreasonable risk of causing this psychic trauma. Thus, plaintiffs have not met the minimal requirements of Bass v. Nooney, supra, and, as now pleaded, this claim is fatally defective.
We do not address nor intend to comment on the extent of plaintiffs' possible problems in properly pleading forseeability here, to say nothing of the complex and formidable problems of proof this pleading entails. See generally G. Nothstein, Toxic Torts § 16.05-.11 (1984).

STRICT LIABILITY
Plaintiffs last Count sounds in strict liability for "ultrahazardous" activities. Restatement of Torts § 519 (1938) creates a claim in strict liability for damages caused by an "ultrahazardous activity." Restatement (Second) of Torts § 519 (1977), however, replaces the term "ultrahazardous" with the term "abnormally dangerous." Our research has not uncovered any Missouri case which expressly accepts or adopts either version of § 519. Nonetheless, we believe strict liability, as defined by the Restatement (Second) of Torts, should be adopted and applied to claims based on radiation damage, and, under this definition, we find plaintiffs have pleaded a claim for relief in strict liability.[12]
The doctrine of strict liability stems from the English case, Rylands v. Fletcher, 1 L.R.-Ex. 265 (1866), aff'd, 3 L.R.-E. & I.App. 330 (1868). The lower court, the Exchequer Chamber, stated the "true rule" of law to be: "the person who for his own purposes brings on his land and collects and keeps there anything likely to do mischief if it escapes, must keep it at his peril, and if he does not do so is prima facie answerable for all the damage which is the natural consequence of its escape." Fletcher v. Rylands, 1 L.R.-Ex. 265, 279-80 (1866). The House of Lords limited the "rule" by making it applicable only to non-natural uses of land. Rylands v. Fletcher, 3 L.R.-E. & I.App. 330, 338 (1868). See also Prosser, Law of Torts § 78, at 505-06 (4th ed. 1971).
As Prosser explains, the "true rule" of Rylands v. Fletcher is the limited rule. It makes the defendant liable "when he damages another by a thing or activity unduly dangerous and inappropriate to the place where it is maintained, in the light of the character of that place and its surroundings." Id. at 508. Sections 519 and 520, Restatement (Second) of Torts (1977), reflect this principle, with § 520 listing six factors pertinent in determining whether an activity is abnormally dangerous.[13]
*868 In Missouri, we have expressly rejected the rule of the Exchequer Chamber, i.e., a defendant is strictly liable when anything under his control escapes and does damage. See, e.g., Kelley v. National Lead Co., 240 Mo.App. 47, 210 S.W.2d 728, 733 (1948); Greene v. Spinning, 48 S.W.2d 51, 61 (Mo. App.1931). Thus, in Missouri, as in many other jurisdictions, the "true rule" of Rylands v. Fletcher has been misstated and, as misstated, has been almost totally rejected, "most often on facts which had no proper application in the first place." Prosser, supra, at 508-09.
Be that as it may, the "rule of Rylands v. Fletcher" is very narrowly applied in Missouri. In blasting cases, for example, a claim for strict liability is as valid a claim as a claim based upon nuisance or trespass. Summers v. Tavern Rock Sand Co., 315 S.W.2d 201 (Mo.1958), Carson v. Blodgett Const. Co., 189 Mo.App. 120, 174 S.W. 447 (1915) (strict liability); Blackford v. Heman Const. Co., 132 Mo.App. 157, 112 S.W. 287 (1908) (nuisance); Johnson v. Kansas City Terminal Ry. Co., 182 Mo. App. 349, 170 S.W. 456 (1914), Faust v. Pope, 132 Mo.App. 287, 111 S.W. 878 (1908) (trespass). But our courts go no further. In other cases, in which plaintiff alleged his damage was caused by an "ultrahazardous" or "abnormally dangerous" thing or activity, our courts have rejected claims based upon strict liability and required the claim to be brought in negligence, nuisance or trespass. See generally II Mo.Tort Law, Chap. 32, Strict Tort Liability (Mo.Bar CLE 1980); Comment, The Rylands v. Fletcher Doctrine and Its Standing In Missouri, 18 Mo.L.Rev. 53 (1953).
Arguably, this history demonstrates a refusal to extend the use of strict liability as a legal tool to hold liable for damages those engaged in abnormally dangerous activities. If this is true, the question here is not would, but rather should, a nuclear plant operator be held strictly liable for his actions? This question is not answered by the usually salutary aphorismif it ain't broke, don't fix it. Theories of liability other than strict liability may serve society better in resolving issues between parties when normal danger is involved. These theories are not equally effective in the nuclear industry.
Understandably, a record was not made for the purpose of determining whether, strict liability, as defined by the Restatement, should be applied here. Certain facts, however, are common knowledge or part of the present record.
The nuclear industry is unique in its inherent and, at present, unrectifiable danger. It is regulated by the federal government. Numerous safety standards have been set to ensure the public welfare, but even with these precautions taken, the potential danger is still enormous. Moreover, as previously noted, the safety standards are not guarantees of absolute safety. Federal emission standards are only guidelines which are based upon an inherently inexact balancing of human and environmental risks against social benefits. See Silkwood, 485 F.Supp. at 581-82; Keyes v. Howarth, supra, at 541, 568. See also 10 C.F.R. § 20.1(c). Each licensee is therefore requested to make every reasonable effort to maintain radiation exposures and releases as low as reasonably achievable. 10 C.F.R. § 20.1(c). The value of the nuclear industry to society may be great, but the use of nuclear material is not yet so common that strict liability should not be applied at this time.[14] This is the basis for the Restatement and Prosser recognizing the nuclear industry is particularly suited for the application of strict liability. See *869 Restatement (Second) of Torts § 520, comments g, h (1977); Prosser, supra, § 78, at 516. In short, the nuclear industry creates dangers as great as blasting operations, if not more so, and, thus, if it fits the criteria established for strict liability, it should be governed by those legal liabilities imposed upon blasting operations because of its danger.
Our Courts have not been deterred in the past from adopting Restatement principles of tort deemed sensible and necessary.[15] We should not be deterred here. Plaintiffs have alleged that Mallinckrodt's activities have created a high degree of risk of harm, the harm has been and will be significant, the risk cannot be eliminated, the harm outweighs the value of the operation of the plant and they have suffered injuries. These are the factors to be considered in a claim for strict liability. Restatement (Second) of Torts §§ 519 and 520 (1977).
The Restatement (Second) of Torts § 519 (1977) speaks of "abnormally dangerous activities," and § 520 lists pertinent factors to determine the appropriateness of the activity in question. The Restatement suggests the court should balance the risks against the benefits and determine, as a matter of law, whether the benefits outweigh the risks. This determination is no different than the determination made by the court when it determines the reasonableness of the use of the land in nuisance cases. See, e.g., Clinic & Hospital, Inc. v. McConnell, 236 S.W.2d 384, 391 (Mo.App. 1951).[16] On remand, the trial court should develop the appropriate record for its determination whether strict liability, as defined by Restatement (Second) of Torts § 520 (1977), should be applied here.[17]

INJUNCTIVE RELIEF
In addition to monetary damages, plaintiffs also seek to enjoin Mallinckrodt's operations. The propriety of this request was not raised as an issue before us. It is clear, however, plaintiffs are not entitled to this injunctive relief. Enjoining Mallinckrodt's operations would effectively establish a state standard, and, as a result, would frustrate federal law. See, e.g., Pennsylvania v. General Public Utilities Corp., 710 F.2d 117, 120 (3d Cir.1983); Crowther v. Seaborg, 312 F.Supp. at 1235.
Judgment reversed. Cause remanded.
SNYDER, P.J., and PUDLOWSKI, J., concur.
ON MOTIONS FOR REHEARING OR, IN THE ALTERNATIVE, FOR TRANSFER TO THE SUPREME COURT
PER CURIAM.
In its motion for rehearing, Mallinckrodt points out that we did not address one of *870 its contentions raised on appeal. This contention centers on statements made by plaintiffs' counsel during oral argument on Mallinckrodt's motion to dismiss. Mallinckrodt asserts these statements clarify and control the meaning of plaintiffs' petition. We were aware of this contention. We read those cases cited by Mallinckrodt in support of its contention and found them to be inapposite. In addition, we note counsel's "clarifying" statements are not part of the designated record but are merely part of an apparent excerpt from the motion hearing appended to Mallinckrodt's brief. On the present facts, we know of no principle of law or logic which requires us to define the explicit meaning of plaintiffs' allegations by the fractional extemporaneous remarks of plaintiffs' counsel. As we noted in our opinion, Mallinckrodt's concern can be alleviated by a motion to make plaintiffs' allegations more definite and certain.
Also, Mallinckrodt once again attempts to support some of its arguments by information which is not part of the record. Once again we note this case is before us only on the trial court's grant of Mallinckrodt's motion to dismiss plaintiffs' petition. If Mallinckrodt wishes to support its arguments by a "Brandeis Brief," it has the proper procedural devices to do so.
Finally, to allay Mallinckrodt's new concern generated by its reading of our opinion, we note that we were and are aware of the difference in potential danger between a reactor meltdown and a radioactive isotope. The present record, however, does not intimate, much less disclose, the potential danger of Mallinckrodt's operation. Our opinion remains unchanged. Strict liability is an appropriate principle for activities generating radioactive emissions. It is for Mallinckrodt to demonstrate to the trial court that its particular activities do not fall within the purview of strict liability as defined by Restatement (Second) of Torts § 520 (1977).
Motions for rehearing and for Transfer to the Supreme Court denied.
NOTES
[1]  In Cipollone, the court describes the development and application of the preemption doctrine in scholarly detail.
[2]  The term "nuclear incident" means:

"any occurrence, including an extraordinary nuclear occurrence ... causing ... bodily injury, sickness, disease, or death, or loss of or damage to property, or loss of use of property, arising out of or resulting from the radioactive, toxic, explosive, or other hazardous properties of source, special nuclear, or byproduct material...." 42 U.S.C. § 2014(q).
[3]  The term "extraordinary nuclear occurrence" means:

"any event causing a discharge or dispersal of source, special nuclear, or byproduct material from its intended place of confinement in amounts offsite, or causing radiation levels offsite, which the Commission determines to be substantial, and which the Commission determines has resulted or will probably result in substantial damages to persons offsite or property offsite." 42 U.S.C. 2014(j).
[4]  Nothing of record shows Mallinckrodt is licensed by the NRC under the Price-Anderson Act.
[5]  The Court also cited Senate Report No. 1605 which reiterates this principle:

Since its enactment by Congress in 1957 one of the cardinal attributes of the Price-Anderson Act has been its minimal interference with State law. Under the Price-Anderson system, the claimant's right to recover from the fund established by the act is left to the tort law of the various States; the only interference with State law is a potential one, in that the limitation of liability feature of the act would come into play in the exceedingly remote contingency of a nuclear incident giving rise to damages in excess of the amount of financial responsibility required together with the amount of the governmental indemnity. S.Rep. No. 1605, 1966 U.S.Code Cong. & Ad. News 3201, 3206.
[6]  Mallinckrodt appears to tacitly admit plaintiffs may state a claim for relief if Mallinckrodt's noncompliance were pleaded. Plaintiffs do allege Mallinckrodt's noncompliance with certain federal regulations but these regulations do not set or affect emission standards.
[7]  See, e.g., Proposed Amendments to Price-Anderson Act Relating to Waiver of Defenses: Hearings before the Joint Committee on Atomic Energy, 89th Cong., 2d Sess. 47 (1966) (statement of Joseph Hennessey, AEC General Counsel); S.Rep. No. 454, reprinted in 1975 U.S.Code Cong. & Ad.News 2251; H.R.Rep. No. 1115, 93d Cong., 2d Sess. 7 (1974). See also H.R.Rep. No. 2043, 89th Cong., 2d Sess. 9-11 (1966).
[8]  These injuries are alleged by plaintiffs in Count I. In Count II, plaintiffs allege the "radiation striking" them has caused and will cause (1) "various health problems ... as well as apprehension and fear" and (2) "permanent and irreparable physical and mental injuries as well as mental anguish and damages." In Count III, they allege their damages are the same "as hereinabove stated."
[9]  For an assault and battery, plaintiffs' Count II, "[t]he establishment of the technical cause of action, even without proof of any harm, entitles the plaintiff to vindication of his legal right by an award of nominal damages." W. Prosser, Torts § 10, at 38 (4th ed. 1971).
[10]  More specifically, plaintiffs plead:

"[they] have suffered apprehension and will continue in the future under severe psychic trauma as a result of their exposure to and the increased risk to the [noted] illnesses."
Obviously, plaintiffs have failed to include several grammatical articles necessary to give this pleading a precise meaning. No useful purpose is served, however, in making these additions a prerequisite to our consideration. We have paraphrased the pleading to reach the issue that would be raised by an appropriate amendment.
[11]  Psychic trauma is defined as:

"an upsetting experience precipitating or aggravating an emotional or mental disorder," Stedman's Medical Dictionary 1476 (24th ed. 1982); or "An emotional injury or shock that leaves a lasting impression on the conscious or subconscious mind. It may cause a permanent change in the personality of the patient." 3 Schmidt's Attorneys' Dictionary of Medicine P-302 (1984).
[12]  As used in the Restatement, the terms "ultrahazardous" and "abnormally dangerous" are terms of art. Each has a separate and distinct definition, but these definitions overlap and are not mutually exclusive. Compare Restatement of Torts § 520 (1938) with Restatement (Second) of Torts § 520 (1977).

No useful purpose is served in affirming the dismissal because plaintiffs used "ultrahazardous" rather than "abnormally dangerous," simply to have plaintiffs replead this claim using the latter and proper term.
[13]  These six factors are:

(a) existence of a high degree of risk of some harm to the person, land or chattels of others;
(b) likelihood that the harm that results from it will be great;
(c) inability to eliminate the risk by the exercise of reasonable care;
(d) extent to which the activity is not a matter of common usage;
(e) inappropriateness of the activity to the place where it is carried on; and
(f) extent to which its value to the community is outweighed by its dangerous attributes.
[14]  Nuclear reactors may never be considered a natural use of the land. On the other hand, nuclear reactors may follow the same path as the "aeroplane," and technological advances and widespread use may make strict liability inapplicable to the nuclear industry as it now is to the use of aeroplanes. See Prosser, supra, § 78, at 514-15.
[15]  See Blevins v. Cushman Motors, 551 S.W.2d 602 (Mo. banc 1977) (products liabilityRestatement (Second) of Torts § 402A); Pretsky v. Southwestern Bell Telephone Co., 396 S.W.2d 566, 568-69 (Mo.1965) (intentional infliction of emotional harmRestatement (Second) of Torts § 48); Porter v. Crawford & Co., 611 S.W.2d 265 (Mo.App.1980) (prima facie tort Restatement (Second) of Torts § 870); Annbar Associates v. American Express Co., 565 S.W.2d 701 (Mo.App.1978) (injurious falsehoodRestatement (Second) of Torts § 623A et seq.).
[16]  "What is a reasonable use of one's property and whether a particular use is an unreasonable invasion of another's use and enjoyment of his property cannot be determined by exact rules, but must necessarily depend upon the circumstances of each case, such as locality and the character of the surroundings, the nature, utility and social value of the use, the extent and nature of the harm involved, the nature, utility and social value of the use or enjoyment invaded, and the like." 236 S.W.2d at 391.
[17]  The factors listed by the Restatement are, as their designation implies, simply factors to be considered by the court. They are not elements of a claim for relief. Restatement, supra, § 520. Forceful argument can be made that factor (f) of § 520social risk weighed against social benefithas been predetermined by the federal government licensing Mallinckrodt's operations, if the operations are in fact licensed.
