What happened at Tokaimura nuclear accident?
The accident was caused by bringing together too much uranium enriched to a relatively high level, causing a ‘criticality’ (a limited uncontrolled nuclear chain reaction), which continued intermittently for 20 hours.
Who was involved in the Tokaimura nuclear accident?
Impact on technicians. According to the radiation testing by the STA, Ouchi was exposed to 17 Sv of radiation, Shinohara 10 Sv, and Yokokawa received 3 Sv. The two technicians who received the higher doses, Ouchi and Shinohara, died several months later.
How many people were affected by tokaimura?
The accident at the Tokai-mura nuclear facility in 1999 irradiated a total of 667 people, two of whom died from acute radiation poisoning.
How much radiation did Hisashi Ouchi have?
about 17 sieverts
The most critically ill of the workers, Hisashi Ouchi, 35, was exposed to about 17 sieverts of radiation, according to the Science and Technology Agency’s National Institute of Radiological Sciences in Chiba, near Tokyo.
Who was the most radioactive person?
Albert Stevens
Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever, was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human.

How did Hisashi Ouchi get radiation?
Hisashi Ouchi was helping a colleague pour litres of uranium into a huge metal vat at the Tokaimura Nuclear Power Plant in 1999. However, due to a miscalculation, the liquid reached ‘critical point’ and released dangerous neutron radiation and gamma rays into the atmosphere.

Where is the highest radiation on Earth?
As of today’s date, 5 of the most radioactive places on earth are:
- Fukishima, Japan. On Friday, March 11, 2011 the Pacific coast of Japan experienced an earthquake with a magnitude upwards of 9.0.
- Chernobyl, Ukraine. Chernobyl was the nuclear event of the 1980s.
