Radiation-induced mutations pass down through generations

Mutations caused by radiation exposure can be found even in the third generation. The results of a mouse study suggests that genetic changes resulting from exposure to high doses of radiation such as X-rays can be inherited by future generations.

Researchers led by Dr. Yuri E. Dubrova of the University of Leicester, UK exposed mice to varying doses of radiation from X-ray and neutron sources. These mice were allowed to mate with unexposed mice to produce offspring. They then analyzed the genome for traces of mutations within their genes. Children and grandchildren of exposed mice demonstrated a higher rate of mutation ... Read more
