At a Glance Researchers found no evidence that radiation exposure from the Chernobyl accident caused genetic changes that were passed on to children. Scientists also found that thyroid cancers arising after radiation exposure were more likely to have certain types of DNA damage. The results further our understanding of the genetic effects of radiation exposure. Researchers used DNA sequencing technology to explore the effects of radiation from the Chernobyl nuclear disaster.

© Shutterstock Chernobyl Nuclear Power Plant Radiation exposure from the 1986 Chernobyl disaster — the world's deadliest nuclear accident — raised the risk of certain mutations linked to thyroid cancer, but it didn't cause new mutations in DNA that parents who cleaned up after the nuclear accident passed along to their children, two new studies find. The new research is a step forward in understanding the mechanisms that drive human thyroid cancer, said Stephen Chanock, the director of the division of cancer epidemiology and genetics at the U.S. National Cancer Institute (NCI) and the ...

Last modified on Fri 23 Apr 2021 14.28 EDT For decades popular culture has portrayed babies born to the survivors of nuclear accidents as mutants with additional heads or at high risk of cancers. But now a study of children whose parents were exposed to radiation from the Chernobyl disaster in 1986 suggests they carry no more DNA mutations than children born to any other parents. The study, published in Science, is one of the first to systematically evaluate alterations in human mutation rates in response to a manmade disaster, such as accidental radiation exposure. As well as providing fresh...

BBC News By Victoria Gill image captionThe study is the first to demonstrate that DNA damage caused by radiation is 'not passed on to future children' There is no "additional DNA damage" in children born to parents who were exposed to radiation from the Chernobyl explosion before they were conceived. This is according to the first study to screen the genes of children whose parents were enlisted to help in the clean-up after the nuclear accident. Participants, all conceived after the disaster and born between 1987 and 2002, had their whole genomes screened. The study found no mutations that ...
