Book excerpt: Children of the Atomic Bomb is Dr. Yamazaki's account of a lifelong effort to understand and document the impact of nuclear explosions on children, particularly the children conceived but not yet born at the time of the explosions. Assigned in 1949 as Physician in Charge of the United States Atomic Bomb Casualty Commission in Nagasaki, Yamazaki had served as a combat surgeon at the Battle of the Bulge where he had been captured and held as a prisoner of war by the Germans. In Japan he was confronted with violence of another dimension - the devastating impact of a nuclear blast and the particularly insidious effects of radiation on children. Yamazaki's story is also one of striking juxtapositions, an account of a Japanese-American's encounter with racism, the story of a man who fought for his country while his parents were interned in a concentration camp in Arkansas.
