A-bomb survivors: further evidence of late effects of early deaths.
Reanalysis of A-bomb survivor data has shown the following: a) in the high-dose (> 1 Gy) subgroups of the life span study cohort of 5-y survivors, there is a significant deficit of individuals who were < 10 y or > 50 y at the time of the bomb; and b) in the cohort on in utero children, there is a significant deficit of individuals who were < 8 wk of fetal age when exposed. This paper discusses how this selection bias has affected the perception of three effects of A-bomb radiation: marrow damage, carcinogenesis, and second-generation effects.
