The Tragic Story of Hisashi Ouchi: Victim of the Worst Nuclear Radiation in History

Jakarta

Hear the name Hisashi Ouchi maybe foreign to the ear. But the story of his death went viral because it was deemed ‘the most painful imaginable’.

Hisashi Ouchi is a technician who works at the Tokaimura Nuclear Power Plant (PLTN), Japan. On September 30, 1999, he and two colleagues, Masato Shinohara and Yutaka Yokokawa, were tasked with purifying uranium oxide at the Tokaimura nuclear fuel processing plant to produce fuel for research reactors.

But an ordinary workday soon turns into a disaster. Ouchi and two co-workers accidentally trigger the release of radiation from an uncontrolled nuclear chain reaction.

The unfortunate incident began when they carried out the process of dissolving and mixing enriched uranium oxide with nitric acid to produce uranyl nitrate, a nuclear fuel. However, they did not follow the correct procedures and added too much uranium to the settling tank.

As a result, the mixture reaches a critical point and triggers a chain nuclear reaction that emits neutron radiation and gamma rays. They saw a bright blue splash on top of the tank and immediately realized that something wrong had happened.

Of the 119 staff members who were exposed to dangerous radiation, Ouchi, who was 35 years old at the time, bore the brunt of the impact of the release. He was the closest person to the tank and was exposed to 17 Sieverts (Sv) of radiation, far exceeding the tolerable limit humans can tolerate.

In comparison, those who first responded to the Chernobyl explosion in 1986 were exposed to only 0.25 sv.

Ouchi immediately felt excruciating pain, vomited, and fainted on the spot. Shinohara and Yokokawa were also exposed to radiation, but with lower doses, namely 10 Sv and 3 Sv.

They were rushed to Mito Hospital, where doctors tried to save their lives. However, Ouchi’s condition was very serious and there was no hope of recovery.

The radiation had damaged his body cells, destroyed his chromosomes, and melted his skin. He also experienced blood loss, infections, kidney failure and cancer.

Despite this, doctors and researchers did not give up and continued to maintain his life using various means, including blood transfusions, skin transplants and heart support machines. They wanted to research the effects of radiation on the human body and find ways to treat it.

However, their efforts were in vain and only added to Ouchi’s suffering. He couldn’t speak, move, or even breathe on his own.

Local reports revealed that he cried blood and begged doctors to take his life. Ouchi experienced clinical death several times, but was always revived by doctors.

“I can’t take it anymore! I’m not a guinea pig!” said Ouchi pleadingly quoted from Unilad.

His bone marrow cells began to show fragmentation and doctors noted that he was unable to regenerate new cells.

Two weeks after the incident, Ouchi could no longer eat food and had to eat through an IV drip.

After 83 days of battling death, Ouchi finally died on December 21, 1999, due to multi-organ failure. He became a victim of the worst nuclear radiation in history and an example of a human being forced to live in torment for the sake of research.
