Chernobyl’s Radiation Legacy: Thyroid Cancer, Genetic Damage, and Long-Term Health Risks

On April 26, 1986, a reactor at the Chernobyl Nuclear Power Plant exploded during a late-night safety test. The blast was brief. The consequences were not. Radioactive material shot into the atmosphere, invisible and odorless, drifting across Ukraine, Belarus, Russia, and much of Europe. Sirens did not warn nearby residents.

Sometimes the body repairs this damage. Sometimes it does not. When repair fails, mutations can…
