299. No chromosomal alteration found in second-generation atomic-bomb survivors

October 10, 2020

Previous investigation demonstrated no detectable genetic effects, such as increased risks of cancer and other diseases, among the atomic bomb survivors’ offspring (the second generation of those who were directly exposed to radiation, also known as the second generation of atomic bomb survivors) in Hiroshima and Nagasaki. This article further explains the findings of these investigations, particularly those relating to the genetic effects on the survivors’ offspring, in detail.

To date, several investigations have been conducted to assess the chromosomal aberrations in the second generation of atomic bomb survivors. Chromosomes are bundles of tightly coiled structures within cells that contain a mass of genetic information.
