Newly released data from the Radiation Effects Research Foundation on the survivors of the Hiroshima and Nagasaki A-bombing allow a reassessment of radiation hazards. It appears that deaths from marrow damage (such as aplastic anaemia) continued after 1950. The Life Span Study cohort appears biased in favour of persons with high immunological competence, the result of infants and the elderly being more likely to die before 1950 than young adults. A study of survivors of in utero exposures suggests that embryos are more sensitive to the lethal effects of radiation than more mature foetuses. Current estimates of cancer risks from radiation may only apply to young adults with high immunological competence; young children and the elderly may be at greater risk.
辐射效应研究基金会公布的有关广岛和长崎原子弹爆炸幸存者的最新数据，使人们能够重新评估辐射危害。1950年以后，因骨髓损伤（如再生障碍性贫血）导致的死亡仍在持续。寿命研究队列似乎偏向于免疫能力强的人，这是因为婴儿和老年人在1950年之前比年轻人更易死亡。一项针对子宫内暴露幸存者的研究表明，胚胎对辐射致死效应的敏感度高于成熟度更高的胎儿。目前关于辐射致癌风险的估计可能仅适用于免疫能力强的年轻人；幼儿和老年人可能面临更大风险。
