North Korean defectors near nuclear site show chromosome mutations in study

A government study has found that about one in four North Korean defectors from areas near the Punggye-ri nuclear test site show signs of chromosome mutations. These findings come from research conducted by South Korea's Ministry of Unification between 2023 and 2025. However

The study began in 2023 as part of broader research into the health of North Korean defectors. Tests measured chromosomal changes to detect possible radiation exposure

The research highlights a possible connection between chromosome mutations and proximity to the Punggye-ri test site. Yet, without verified cases of radiation sickness or proof of exposure, the findings remain inconclusive. The Ministry of Unification continues to monitor the situation as part of its ongoing study.
