During the response to the Fukushima Daiichi nuclear power plant (FDNPP) emergency, about 50 patients died during or shortly after an evacuation when they were not provided with the needed medical support. In addition, it has been shown that during the FDNPP emergency there were increases in mortality rates among the elderly due to long-term dislocation as a result of evacuation and relocation orders and an inability to stay in areas where residents were advised to shelter for extended periods. These deaths occurred even though the possible radiation exposure to the public was too low to result in radiation-induced deaths, injuries, or a meaningful increase in the cancer rate, even if no protective actions had been taken. These problems are not unique to the FDNPP emergency and would be expected if the recommendations of many organizations were followed. Neither the International Commission on Radiological Protection (ICRP), the U.S. Nuclear Regulatory Commission (NRC) nor the U.S Environmental Protection Agency (EPA) adequately take into consideration in their recommendations and analysis the non-radiological health impacts, such as deaths and injuries, that could result from protective actions. Furthermore, ICRP, NRC, EPA, and the U.S. Department of Homeland Security (DHS) call for taking protective actions at doses lower than those resulting in meaningful adverse radiation-induced health effects and do not state the doses at which such effects would be seen. Consequently, it would be impossible for decision makers and the public to balance all the hazards both from radiation exposure and protective actions when deciding whether a protective action is justified. What is needed, as is presented in this paper, is a method for developing a comprehensive protective action strategy that allows the public, decision makers, and others who must work together to balance the radiological with the non-radiological health hazards posed by protective actions, and to counter the exaggerated fear of radiation exposure that could lead to taking unjustified protective actions and adverse psychological, sociological, and other effects.
在应对福岛第一核电站(FDNPP)事故紧急情况期间,约50名患者在疏散过程中或疏散后不久死亡,当时他们没有得到所需的医疗支持。此外,研究表明,在福岛第一核电站事故紧急情况期间,由于疏散和重新安置命令导致长期流离失所,以及无法留在建议居民长时间避难的地区,老年人的死亡率有所上升。即使公众可能受到的辐射暴露水平过低,即使不采取防护措施也不会导致辐射诱发死亡、受伤或癌症发病率显著上升,但这些死亡事件仍有发生。这些问题并非福岛第一核电站事故紧急情况所独有,如果遵循许多组织的建议,预计也会出现此类问题。国际放射防护委员会(ICRP)、美国核管理委员会(NRC)和美国环境保护局(EPA)在其建议和分析中均未充分考虑防护行动可能导致的非辐射健康影响,如死亡和受伤。此外,ICRP、NRC、EPA和美国国土安全部(DHS)呼吁在低于产生有意义的辐射诱发不良健康影响的剂量下采取防护行动,且未说明会出现此类影响的剂量。因此,决策者和公众在决定一项防护行动是否合理时,不可能平衡辐射暴露和防护行动带来的所有危害。正如本文所提出的,需要一种制定全面防护行动策略的方法,使公众、决策者和其他必须共同努力的各方能够平衡防护行动带来的辐射健康危害与非辐射健康危害,并消除对辐射暴露的过度恐惧,这种恐惧可能导致采取不合理的防护行动以及产生不良的心理、社会和其他影响。
