Who is Hisashi Ouchi?
Hisashi Ouchi was a Japanese nuclear technician who suffered a criticality accident (hisashi ouchi face) at the Tokaimura Nuclear Power Plant in 1999. He received the highest possible dose of radiation that a human being has ever survived, estimated at 17 sieverts (Sv), and lived for 83 days after the accident.
Background
Ouchi was born on May 23, 1967, in Hokkaido, Japan. He began working at the Tokaimura Nuclear Power Plant in 1990 as a nuclear fuel processing technician. On September 30, 1999, Ouchi and two other technicians were involved in a criticality accident while attempting to manually enrich uranium.
The Accident
The criticality accident occurred when the technicians added too much uranium to a precipitation tank, causing a runaway nuclear chain reaction. Ouchi was standing closest to the tank and received the highest dose of radiation.
Aftermath
Ouchi was rushed to the University of Tokyo Hospital, where he underwent extensive treatment for his radiation injuries. However, his condition continued to deteriorate, and he died on December 21, 1999, at the age of 32.
Legacy
Ouchi's case is a reminder of the dangers of working with radioactive materials. It has also led to changes in safety procedures at nuclear power plants around the world.
