Who was Hisashi Ouchi and what made his case significant?
Hisashi Ouchi was a Japanese nuclear technician who, in 1999, was accidentally exposed to a critical mass of uranium, resulting in a radiation overdose that caused multi-organ failure and led to his death. His case gained international attention due to its extreme severity and the extensive medical efforts made to save his life.
Ouchi's exposure occurred during a uranium enrichment experiment at a nuclear fuel processing facility. He was operating a uranium processing machine when a chain reaction occurred, releasing a burst of radiation that engulfed his body. The radiation dose he received was estimated to be 17 sieverts, which is more than 10 times the lethal dose for humans.
Ouchi was rushed to the University of Tokyo Hospital, where he underwent aggressive medical treatment, including multiple surgeries and blood transfusions. However, his condition continued to deteriorate as the radiation damage spread throughout his body. He experienced severe burns, organ failure, and a compromised immune system. Despite the best efforts of the medical team, Ouchi died three months after the accident.
