What is hisashi ouchi?

Hisashi Ouchi was a Japanese technician who worked at the <a href="https://www.wikiwhat.page/kavramlar/Tokaimura%20nuclear%20accident">Tokaimura nuclear accident</a> fuel reprocessing facility in Tokai, Ibaraki Prefecture. He became critically irradiated on September 30, 1999, during a <a href="https://www.wikiwhat.page/kavramlar/nuclear%20reprocessing">nuclear reprocessing</a> procedure when an excessive amount of uranium solution was added to a precipitation tank.

Ouchi received an estimated radiation dose of 17 Sieverts (17,000 mSv), which is significantly higher than the lethal dose for humans. He experienced severe and agonizing <a href="https://www.wikiwhat.page/kavramlar/radiation%20sickness">radiation sickness</a>, including chromosomal damage, a drastically weakened immune system, and internal organ failure.

Despite extensive medical intervention and experimental treatments, Ouchi's condition continued to deteriorate. His case sparked ethical debates about the extent to which life-sustaining treatment should be pursued in hopeless situations. He ultimately died 83 days after the accident due to multiple organ failure. His ordeal highlighted the dangers of <a href="https://www.wikiwhat.page/kavramlar/nuclear%20safety">nuclear safety</a> breaches and the devastating effects of high-dose radiation exposure.
