In 1999, Japanese worker Hiroshi Ouchi received a deadly radiation dose when material he was working with became critical. He was exposed to so much radiation that even his chromosomes were destroyed. However, he did not get a quick death. Instead, doctors kept him alive to observe the effects of radiation on a person’s health. His skin and muscles slowly began to fall apart and his intestines began to melt. After 10 days, he begged for death, shouting “I can’t take it anymore; I’m not a guinea pig”. His suffering continued for 3 months.
