Hisashi Ouchi, a Japanese nuclear technician, became the first person to die from acute radiation syndrome in Japan after a criticality accident in 1999. The accident occurred at the JCO uranium reprocessing plant in Tokaimura, Ibaraki, where Ouchi was working with a uranium solution when it became critical, releasing a burst of neutrons and gamma rays.

Severity of radiation exposure: 17 sieverts of radiation is an extremely high dose, and it is more than 10 times the lethal dose. This means that Ouchi's exposure was fatal.
Effects of radiation exposure: Radiation exposure can cause a variety of health effects, including skin damage, hair loss, nausea, vomiting, diarrhea, and fatigue. In severe cases, radiation exposure can lead to acute radiation syndrome, which can be fatal.
Treatment for radiation exposure: There is no specific cure for radiation exposure, but treatment can help to relieve symptoms and prevent complications. Treatment may include supportive care, such as fluids, electrolytes, and pain medication, as well as specific treatments for the symptoms of radiation exposure, such as antibiotics for infections and blood transfusions for anemia.
Prevention of radiation exposure: The best way to prevent radiation exposure is to avoid exposure to sources of radiation, such as nuclear power plants and radioactive materials. When exposure to radiation is unavoidable, it is important to take steps to minimize the dose, such as wearing protective clothing and using shielding.

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

Medical treatment: Ouchi underwent intensive treatment for radiation sickness at the University of Tokyo Hospital.

Hisashi Ouchi's medical treatment was a key part of his story.
