Biography of Hisashi Ouchi
Personal Information
Hisashi Ouchi was a 35-year-old worker at the JCO nuclear fuel processing plant in Tokaimura, Japan. Below is a summary of his personal information:
| Name | Hisashi Ouchi |
|---|---|
| Age at Time of Incident | 35 years |
| Occupation | Worker at JCO Nuclear Fuel Processing Plant |
| Place of Incident | Tokaimura, Japan |
| Date of Incident | September 30, 1999 |
Hisashi Ouchi was an ordinary worker whose life took a tragic turn due to a catastrophic event at his workplace. His story has become a pivotal reference point in discussions about nuclear safety and radiation exposure.
The Tokaimura Radiation Accident
What Happened?
The Tokaimura accident occurred on September 30, 1999, when workers at the JCO plant mixed uranium solution in a precipitation tank, exceeding critical mass. This led to an uncontrolled nuclear chain reaction, releasing lethal doses of radiation. Hisashi Ouchi, along with two other workers, was exposed to extremely high levels of radiation.
According to reports, Ouchi received a dose of approximately 17 sieverts, far exceeding the lethal limit of 5 sieverts. The incident was classified as a Level 4 "accident with local consequences" on the International Nuclear Event Scale (INES).
Effects of Radiation on the Human Body
Short-Term and Long-Term Effects
Radiation exposure has devastating effects on the human body. In the case of Hisashi Ouchi, the immediate effects included severe burns, organ failure, and damage to DNA. Here are some key points:
- Severe damage to skin and tissues
- Massive blood loss and anemia
- Disruption of cellular functions
- Increased risk of cancer and genetic mutations
Long-term effects can include chronic illnesses, psychological trauma, and reduced life expectancy. Ouchi's condition deteriorated rapidly, highlighting the extreme dangers of high-dose radiation exposure.
