In August, 1945, the US used the only two nuclear weapons ever used in warfare. Ran across this note in Wikipedia-
People who suffered the effects of both bombings are known as nijū hibakusha in Japan. On March 24, 2009, the Japanese government officially recognized Tsutomu Yamaguchi (19162010) as a double hibakusha. He was confirmed to be 3 kilometers from ground zero in Hiroshima on a business trip when Little Boy was detonated. He was seriously burnt on his left side and spent the night in Hiroshima. He arrived at his home city of Nagasaki on August 8, a day before Fat Man was dropped, and he was exposed to residual radiation while searching for his relatives. He was the first officially recognised survivor of both bombings. Tsutomu Yamaguchi died on January 4, 2010, after a battle with stomach cancer at the age of 93.
