– Atmospheric dose of reactor4 pool area is nearly 0.1 mSv/h / Reaches the annual dose limit only within 200 hours (Fukushima Diary, Feb 6, 2014):
Following up this article.. NRA “Radiation dose is too high in reactor4 spent fuel pool area” → Tepco covered lead plate over the crane [URL]
The radiation dose on the “stand” above reactor4 pool is 90 μSv/h, according to NRA (Nuclear Regulation Authority).
The annual dose limit of workers is 20 mSv. The total exposure dose of fuel removing workers will reach this annual limit only within 200 hours.
Tepco is to keep removing the fuel until the end of this year.
However, Tepco announced they will not release the exposure dose data of the workers. The reason is not announced either.
(cf, Tepco not to announce the total exposure dose of workers for reactor4 pool fuel removing [URL])
