South Korea and Japan will conduct a joint genetic study on the children of Korean people who were exposed to radiation when the U.S. dropped atomic bombs on Japan at the end of World War Two in 1945.

Japanese newspaper the Asahi Shimbun reported that a research team of academics and medical doctors from the two countries will collect blood samples from the children of 100 Koreans who were bombed in Hiroshima and Nagasaki. The team will begin analyzing the samples sometime this year at the earliest.

This marks the first joint study by South Korea and Japan on the descendants of Korean bombing victims.
