  • Mental retardation is the most prevalent abnormality to appear in prenatally exposed humans.


  • There is a 4% chance of occurrences per 0.1 Sv (10 rem) at 8-15 weeks of gestational age.


  • There is less risk with exposures at other gestational ages.


  • This information comes from the BEIR V report by National Academy of Sciences, 1990.


  • Children conceived after exposure to parents who received large exposures have shown no effect above normal incidence of mental retardation.
