Hisashi Ouchi, a lab technician who becomes nation’s worst-ever nuclear radiation victim during an accident in a nuclear power plant of Japan. It is considered to be an extremely critical issue of nuclear effect in our medical history, where Hisashi was kept alive for 83 days in some experimental ways. A number of questions remain about the ethics surrounding his treatment.

Cause Of The Second Tokaimura Nuclear Accident:

The Second Tokaimura Nuclear Accident conveys the nuclear disaster that occurred on September 30 1999, at around 10:35am, resulting in two horrific nuclear deaths. It is one of the world’s worst civilian nuclear radiation accidents that happened in a uranium fuel reprocessing plant. The plant was operated by Japan Nuclear Fuel Conversion Co. located at Tokai village of Naka District, in Japan.

Three lab workers, Hisashi Ouchi, 35 years old, Yutaka Yokokawa, 54 years old, and Masato Shinohara, 39 years old, were working at the lab in their shift that day. Hisashi and Masato were together preparing a measurable batch of nuclear-fuel by adding uranium solution to the precipitation tanks. Due to lack of experience, they had mistakenly added an excessive quantity of uranium to one of those tanks which reached to its critical condition. Eventually, in all of sudden, a self-sustaining nuclear chain reaction started with an intense blue flash and the horrible accident took place.

The Fate Of Hisashi Ouchi:

Unfortunately, Hisashi was the nearest one from the explosion who was injured most. He received 17 sieverts of radiation while 50 mili sieverts is considered as the maximum permissible annual dose of radiation and 8 sieverts is considered as the mortal-dose. Whereas, Masato and Yutuka also received the fatal doses of 10 sieverts and 3 sieverts respectively. They all were immediately admitted to the Mito Hospital.

Hisashi suffered 100% of serious burns, and most of his internal organs were fully or partially damaged. Shockingly the white blood cell count in his body was near to zero, destroying his whole immune system, and the fatal radiation also destroyed his DNA.
