Theseguideline levels apply to food after reconstitution or as prepared for consumption, i.e., not to dried orconcentrated foods, and are based on an intervention exemption level of 1 mSv in a year.

  52. 52. j E4/4/11: Based on the Section 1 of the Article 64 of the Nuclear Reactor Regulation Law, we have decided to discharge to the sea approximately ten thousand tons of the accumulated low level radioactive water and a total of 1,500 tons of the low level radioactive subsurface water stored in the sub drain pits of Unit 5 and 6 as soon as we get ready. We evaluate approximately 0.6 mSv of effective radioactive doses per year for adults as the impact on the discharge of the low radioactive waste water to the sea if they eat adjacent fish and seaweeds every day. The amount (0.6 mSv of effective radioactive doses per year) is one-forth of annual radioactive dose to which the general public is exposed in nature. rate: 300 tons / day6/4/11: 5.38 Se ha tapado la fisura encontrada días antes 9:00 Se planea inyectar N2 en U1 pues se sospecha que hay H2 en su interior
