Frequently Asked Questions

Are radiation-induced cancers still occurring among atomic-bomb survivors?
Cancers attributable to radiation are still occurring among A-bomb survivors. The excess risk of leukemia, seen especially among those exposed as children, was highest during the first ten years after exposure, but has decreased over time and has now virtually disappeared. In contrast, excess risk for cancers other than leukemia (solid cancers) has stayed constant and seems likely to persist throughout the lifetime of the survivors.
