no increase is expected in the incidence of congenital or developmental abnormalities, including cognitive impairment attributable to within the womb radiation exposure. as no radiation induced inherited effects/heritable effects, nor teratogenic effects, have ever been definitely demonstrated in humans, with studies on the health of children conceived by cancer survivors who received radiotherapy, and the children of the hibakusha, not finding a definitive increase in inherited disease or congenital abnormalities. no increase in these effects are therefore expected in or around the fukushima power plants.
