Human rights advocates on Tuesday urged South Korea to offer radiation exposure tests to hundreds of North Korean escapees who had lived near the country’s nuclear testing ground.
Tests conducted by the South Korean government on 40 people in 2017 and 2018 found at least nine of them had abnormalities that could indicate high radiation exposure, but Seoul's Unification Ministry said a conclusive link to North Korea's nuclear activity couldn't be established and other factors were possible, such as age, smoking habits or other types of chemical exposure.
