The reasoning that developed in the 1950s at the beginning of the cold war was a nuclear weapon cost a small fraction of a division of troops yet could substitute effectively for it. This eventually allowed Eisenhower to reduce US Military manpower significantly, as our stockpile grew. When damage from atomic bombs was first considered, our congress and the public were deeply impressed by pictures of genetic monsters in fruit flies which had received excessive doses of ionizing radiation. This started radiation hysteria, provided abundant money for research on harm from ionizing radiation, and effectively stopped support for research on the benefits of low dose irradiation (Brucer, 1990). Excess radiation did cause radiation sickness and death in Japanese victims of atomic bombs.

However, no genetic monsters were found in children from exposed parents. After half a century of study, no statistically significant effects were found in congenital defects, stillbirth, leukemia, cancer, offspring death rates, sex ratio, growth and development during childhood, chromosomal aneuploidy and translocations, or mutations. An exquisitely sensitive test was preformed for point mutations of DNA as reflected in serum proteins. No effect was found in 298,868 individual tests in children exposed to a variety of different doses of ionizing radiation from atomic bombs (Neel et al., 1980, Schull et al. 1981).

Data from the Radiation Effects Research Foundation (RERF) in Hiroshima showed that lightly exposed fetuses had fewer phenotypic abnormalities than were found in controls (fig. 1) (Schull et al., 1981). When compared with the control population, Schull and associates noted that Japanese children born from mothers exposed to low doses of ionizing radiation had fewer stillbirths, congenital effects, and neonatal deaths. The threshold (ZEP is the zero equivalent point) was about 100 cGy to the ovary. These results were obtained when exposures of the fathers was <10 cGy.
