  •  2 workers near 250 millisievert radiation limit (4+ / 0-)

    There is mention of "internal" exposure which leads one to question whether TEPCO is providing the proper respirators to its workers. It also seems that TEPCO is only using robotic technology in cases where using a human worker is totally out of the question. They don't seem to using robots and remotely operated vehicles to conserve their workforce for tasks that are ill-suited for robotic work.

    Radiation exposure level nears limit for 1 worker at Fukushima plant | Kyodo News

    April 30, Kyodo

    ...
    TEPCO, as the firm is known, said it found that the amount of internal and external radiation exposures of one of its employees working at the plant, crippled by the March 11 killer earthquake and ensuing tsunami, had reached 240.8 millisieverts in total, while another received 226.6 millisieverts.

    Under Japanese law, nuclear workers cannot be exposed to more than 250 millisieverts per year in an emergency situation. To cope with the Fukushima crisis, the Ministry of Health, Labor and Welfare raised the legal limit of radiation that each worker could be exposed to in such situation from 100 millisieverts on March 15.
