On September 30, 1999, Hisashi Ouchi was exposed to the highest dose of nuclear radiation in human history. A 35-year-old lab technician at the nuclear plant in Tokaimura, Japan, Ouchi was mixing a uranium solution by hand directly over an open container when he accidentally poured in too much uranium, immediately causing a violent explosion. For the next 83 days, Ouchi suffered unimaginable agony as the radiation worked its way through his body, obliterating his DNA and causing his skin to melt off and his eyes to weep blood before he finally died. And though he begged for death, doctors refused to listen and kept him alive against his will for nearly three excruciating months.
