What happened to Hisashi Ouchi after radiation exposure?

Hisashi Ouchi was a Japanese nuclear technician who suffered a criticality accident in 1999. The accident occurred when Ouchi and a colleague were working on a uranium enrichment plant. Ouchi was exposed to a massive dose of radiation, estimated to be between 17 and 18 sieverts (Sv). This is more than 10 times the lethal dose for humans.

Ouchi's body was severely damaged by the radiation. He suffered from acute radiation syndrome, which caused his skin to peel off, his internal organs to fail, and his immune system to collapse. Ouchi underwent multiple surgeries and treatments in an attempt to save his life, but he died three months after the accident.

Ouchi's case is a reminder of the dangers of radiation exposure. Radiation can cause serious health problems, including cancer, birth defects, and death. It is important to take precautions to avoid exposure to radiation, such as wearing protective clothing and following safety procedures.

The accident at the uranium enrichment plant also highlighted the need for better safety measures at nuclear facilities. Since the accident, new safety regulations have been put in place to help prevent similar accidents from happening in the future.
