When Shin Jin Tae's first daughter died, her mother was still breast-feeding her.
"She became thinner and thinner until she passed away," the 62-year-old farmer says. When more mysterious diseases and inexplicable deaths occurred in Hapcheon county where he lives, Shin started to think that all this might be related to the past.
Shin was born in Hiroshima. When the atomic bomb was dropped on Aug. 6, 1945, he was two years old.
