The Incident: A Criticality Accident

On September 30, 1999, a group of workers, including Hisashi Ouchi, were involved in a criticality accident while handling uranium at the Tokaimura nuclear facility. The workers mistakenly mixed a large amount of uranium in a container without following proper safety protocols. This action triggered a rapid nuclear chain reaction, resulting in a massive release of radiation.

At the time of the incident, Ouchi was exposed to an estimated 17 sieverts of radiation, a level far beyond what is considered survivable. The immediate effects were catastrophic, leading to severe burns and the rapid onset of radiation sickness. Hisashi and two other workers were rushed to a hospital where they received emergency care.

The incident prompted a nationwide response and raised alarms about the safety practices in the nuclear industry. The Japanese government and the Tokyo Electric Power Company (TEPCO) faced immense scrutiny and criticism regarding the lack of safety measures in place at the facility.

Immediate Consequences of the Incident

Severe radiation exposure led to organ failure in Hisashi Ouchi.
Two other workers also suffered from radiation sickness but survived.
The facility was temporarily shut down for investigations.

Medical Treatment and Aftermath

Hisashi Ouchi's injuries were so severe that he required extensive medical treatment. He was placed in a sterile room to avoid infections, and doctors attempted various treatments to alleviate his suffering. Despite their best efforts, Ouchi's condition continued to deteriorate due to the effects of radiation.

Hisashi Ouchi's story became widely known as he fought for his life. The media followed his case closely, bringing attention to the realities of radiation sickness and the human cost of industrial accidents. Tragically, Ouchi succumbed to his injuries on December 21, 1999, after nearly three months in the hospital.

Medical Procedures Undertaken

Isolation in a sterile environment to prevent infections.
Blood transfusions and treatments to combat radiation sickness.
Pain management and psychological support for Ouchi and his family.
