Who is Hisashi Ouchi?
Hisashi Ouchi was a Japanese nuclear technician who suffered a criticality accident at the Tokaimura Nuclear Power Plant in 1999. The accident resulted in his exposure to a massive dose of radiation, which led to a prolonged and painful death. Ouchi's case is one of the most severe radiation accidents in history, and it highlights the dangers of working with radioactive materials.
Ouchi was born in 1960 in Ibaraki, Japan. He began working at the Tokaimura Nuclear Power Plant in 1983. On September 30, 1999, Ouchi was involved in an accident while working with uranium hexafluoride, a highly radioactive material. The accident occurred when Ouchi and two other technicians were trying to dissolve the uranium hexafluoride in a nitric acid solution. The reaction between the two chemicals caused a criticality accident, which released a burst of radiation.
Ouchi was exposed to a massive dose of radiation, estimated to be around 17 sieverts (Sv). This is more than 10 times the lethal dose of radiation. The radiation damaged Ouchi's cells and tissues, and it caused him to develop a number of serious health problems, including acute radiation syndrome, multiple organ failure, and bone marrow failure.
Ouchi was hospitalized for several months after the accident. He underwent a number of treatments, including skin grafts and blood transfusions. However, his condition continued to deteriorate, and he died on December 21, 1999.
Ouchi's death was a tragedy. It highlighted the dangers of working with radioactive materials, and it led to a number of changes in safety procedures at nuclear power plants. Ouchi's case is a reminder of the importance of radiation safety, and it is a testament to the courage of those who work with radioactive materials.
