Who is Hisashi Ouchi?

Hisashi Ouchi was a Japanese nuclear technician who suffered a criticality accident at the JCO Tokaimura plant in 1999. He is known for being the person with the highest recorded radiation dose in human history and for surviving for 83 days after the accident.

Ouchi's accident occurred when he was working with uranium fuel in a uranium processing facility. He accidentally dropped a uranium solution into a precipitation tank, which caused a chain reaction and released a large amount of radiation. Ouchi was exposed to an estimated 17 sieverts of radiation, which is more than 10 times the lethal dose.

Ouchi was immediately taken to the University of Tokyo Hospital, where he received intensive medical treatment. However, his condition continued to deteriorate, and he died on December 21, 1999, from multiple organ failure.

Ouchi's case is a reminder of the dangers of radiation and the importance of following safety procedures when working with radioactive materials.
