Biography of Hisashi Ouchi
Hisashi Ouchi was born on March 1, 1962, in Japan. Before the tragic accident, he was a dedicated worker at the JCO Nuclear Fuel Processing Plant in Tokai-mura. Ouchi was known for his commitment to his job and his willingness to take on challenging tasks. His life took a drastic turn on September 30, 1999, when he became the victim of one of the worst radiation accidents in history.
Below is a table summarizing Hisashi Ouchi's personal data and professional background:
| Full Name | Hisashi Ouchi |
|---|---|
| Date of Birth | March 1, 1962 |

The Tokai-mura Criticality Accident
The Tokai-mura criticality accident occurred on September 30, 1999, at the JCO Nuclear Fuel Processing Plant in Tokai-mura, Japan. This incident was caused by a series of human errors and procedural violations during the preparation of uranium fuel. Hisashi Ouchi, along with two other workers, was exposed to lethal levels of radiation when an uncontrolled nuclear chain reaction took place.
What Happened During the Accident?
During the accident, workers bypassed safety protocols by manually mixing uranium powder with nitric acid in a precipitation tank. This improper procedure led to a criticality event, releasing a massive amount of neutron radiation. Hisashi Ouchi, who was closest to the source, received an estimated radiation dose of 17 sieverts (Sv), far exceeding the lethal dose of 5 Sv.
Immediate Aftermath
- Hisashi Ouchi and his colleague, Masato Shinohara, were hospitalized immediately after the accident.
- The third worker, Yutaka Yokokawa, received a lower dose of radiation but still required medical attention.
- The surrounding area was evacuated, and residents within a 350-meter radius were advised to stay indoors.
Medical Treatment and Ethical Dilemmas
Hisashi Ouchi's medical treatment became a subject of intense debate due to the unprecedented nature of his injuries. The radiation exposure caused severe damage to his DNA, leading to extensive burns, organ failure, and a compromised immune system.
Initial Medical Interventions
Upon arrival at the hospital, Ouchi was placed in an isolation unit and subjected to intensive medical care. Doctors attempted to stabilize his condition through blood transfusions, skin grafts, and other life-support measures. However, the extent of his injuries made recovery nearly impossible.
