Nuclear plant workers developed cancer despite lower radiation exposure than legal limit, Mainichi Daily News, July 27, 2011:
Of 10 nuclear power plant workers who have developed cancer and received workers’ compensation in the past, nine had been exposed to less than 100 millisieverts of radiation, it has been learned. [...]
According to Health, Labor and Welfare Ministry statistics, of the 10 nuclear power plant workers, six had leukemia, two multiple myeloma and another two lymphatic malignancy. Only one had been exposed to 129.8 millisieverts but the remaining nine were less than 100 millisieverts, including one who had been exposed to about 5 millisieverts.
Nobuyuki Shimahashi, a worker at the Hamaoka Nuclear Power Plant:
[Shimahashi] died of leukemia in 1991 at age 29. His 74-year-old mother Michiko remembers her son dropping from 80 kilograms to 50 kilograms and his gums bleeding. [...]
He had 50.63 millisieverts of radiation exposure over a period of eight years and 10 months.
His radiation exposure monitoring databook, which was returned to his family six months after his death, showed that more than 30 exposure figures and other listings had been corrected in red ink and stamped with personal seals.
Even after he was diagnosed with leukemia, the databook had a stamp indicating permission for him to engage in a job subject to possible radiation exposure and a false report on his participation in nuclear safety education while he was in reality in hospital.
