International Research Teams Explore Genetic Effects of Chernobyl Radiation
The research used next-generation DNA sequencing and other genomic characterization tools to analyze biospecimens from people in Ukraine who were affected by the disaster
May 21, 2021
In two landmark studies, researchers have used cutting-edge genomic tools to investigate the potential health effects of exposure to ionizing radiation, a known carcinogen, from the 1986 accident at the Chernobyl nuclear power plant in northern Ukraine. One study found no evidence that radiation exposure to parents resulted in new genetic changes being passed from parent to child. The second study documented the genetic changes in the tumors of people who developed thyroid cancer after being exposed as children or fetuses to the radiation released by the accident.

How Did the Chernobyl Disaster Affect Human Health?
It s been about 35 years since the disaster at the Chernobyl nuclear power plant. Now researchers have investigated whether exposure to ionizing radiation released in the accident caused lasting effects in the genomes that were passed from exposed parents to their children. A second study focused on cancerous thyroid tumors that developed in people that were exposed to the radiation as children or neonates. The findings, which suggested that the radiation exposure did not cause intergenerational impacts and that certain genes drove thyroid tumor development in those that got cancer, have been reported in two research studies in

The findings, published around the 35th anniversary of the disaster, are from international teams of investigators led by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health. The studies were published online in
