Who is Hisashi Ouchi?

Hisashi Ouchi was a Japanese nuclear technician who suffered a criticality accident at a uranium reprocessing facility in 1999. He is the only person in history to have survived more than 83 days after being exposed to such a high dose of radiation.

Hisashi Ouchi's full body was exposed to radiation, resulting in a dose of 17 sieverts (Sv) to his entire body and 20 Sv to his upper body. This unprecedented exposure caused a severe and complex combination of radiation injuries, including burns, internal organ damage, and bone marrow failure.

In the aftermath of the accident, Ouchi received aggressive medical treatment, including multiple surgeries, skin grafts, and blood transfusions. However, his condition worsened over time, and he died from multiple organ failure 83 days after the accident.

Hisashi Ouchi's case is a tragic reminder of the devastating effects of radiation exposure. It highlights the importance of proper safety procedures and the need for continued research on the treatment of radiation injuries.
