Accident

A criticality accident is an uncontrolled nuclear chain reaction that occurs outside of a nuclear reactor. It can happen when fissile material, such as uranium or plutonium, is brought together in a way that allows a chain reaction to start. Criticality accidents can release large amounts of radiation, which can be harmful to human health.

Uncontrolled nuclear chain reaction: In a criticality accident, the nuclear chain reaction is not controlled, which means that it can continue to grow until it is stopped by outside intervention.
Release of large amounts of radiation: Criticality accidents can release large amounts of radiation, which can be harmful to human health. Radiation can cause a variety of health problems, including radiation burns, acute radiation syndrome, and cancer.
Hisashi Ouchi's accident: Hisashi Ouchi was involved in a criticality accident at the Tokaimura Nuclear Power Plant in Japan on September 30, 1999. He was working with uranium when he accidentally dropped a container of the radioactive material, which resulted in a criticality accident. Ouchi was exposed to a massive dose of radiation, estimated to be around 17 sieverts (Sv), which is more than 10 times the lethal dose.

Criticality accidents are rare, but they can have devastating consequences. The Hisashi Ouchi accident is a reminder of the importance of following safety protocols and procedures when working with radioactive materials.

Exposure

Hisashi Ouchi was exposed to an estimated 17 sieverts (Sv) of radiation, over 100% of his body. This massive dose of radiation caused extensive radiation burns and organ damage, leading to his death 83 days after the accident.

Severity of exposure: 17 Sv is an extremely high dose of radiation. The average person receives about 0.02 Sv of radiation per year from natural sources. A single dose of 1 Sv can cause acute radiation syndrome, which can be fatal.
: Ouchi's exposure was over 100% of his body. This means that every part of his body was exposed to a high dose of radiation. This type of exposure is particularly dangerous because it can cause damage to multiple organs and systems.
Radiation burns: Radiation burns are a type of radiation injury that occurs when the skin is exposed to a high dose of radiation. Ouchi's radiation burns were so severe that they covered over 100% of his body.
Organ damage: Radiation can also damage internal organs. Ouchi's exposure caused damage to his lungs, heart, and other organs.
