He had been helping Masato Shinohara pour the radioactive liquid into the vat, while another colleague, Yutaka Yokokawa, had been working at a desk four metres away.

When Hisashi Ouchi arrived at the University of Tokyo Hospital after being exposed to the highest level of radiation of any human in history, doctors were stunned. Rads or grays reflect the amount of radiation absorbed, while rems and sieverts reflect the relative biological damage caused by the dose, according to MIT News. They had all been directly exposed to the radiation, but because of their proximity to the fuel, they each were irradiated at different degrees. Photographs of Hisashi Ouchi's chromosomes show them completely decimated. [19] The two technicians who received the higher doses, Ouchi and Shinohara, died several months later. The steps included feeding small batches of uranium oxide powder into a designated dissolving tank in order to produce uranyl nitrate using nitric acid. Ouchi and Shinohara immediately experienced pain, nausea, and difficulty breathing; both workers went to the decontamination room where Ouchi vomited.
