It has been known for some time, through that radiation causes cataracts in animals. But cataracts developed in human beings after the atomic bombings in Hiroshima and Nagasaki.
According to a clinical report of 128 cataract cases in Hiroshima during the four years from 1957, 38.3% had atomic bomb cataracts or suspected atomic bomb cataracts. It is reported that 70% of those were within 1 kilometer from the hypocenter, and 30% were within 2 kilometers.
