He was about to suffer a horrifying fate that would become a cautionary lesson of the perils of the Atomic Age. [1], The next morning, workers ended the nuclear chain reaction by draining water from the surrounding cooling jacket installed on the precipitation tank. However, the gravity of that event would be dwarfed two short years later. Finally, after 83 days of suffering, Hisashi Ouchi succumbed to multi-organ failure on December 21st, 1997. Shinohara, Ouchi's co-worker, died in April 2000 of multiple organ failure as well, according to The Guardian. Shinohara spent seven months fighting for his life.
