Today we submitted a report on the exposure dose evaluation as of the end of October 2013 to the Ministry of Health, Labor and Welfare.
- The number of workers newly engaged in October was 561. The maximum external exposure dose was 15.22mSv, and no significant value was measured for the internal exposure.

* The workers who applied Emergency dose limit (100mSv) shown in "Ordinance on Prevention of Ionizing Radiation Hazards, chapter 7." Specifically, it means the workers who engaged in the work to maintain the function that cooling reactor facility or spent fuel tank at the area where the radiation dose exceed 0.1 mSv/h and reactor facility, steam turbine and related facilities and surrounding area in the power plant or the work to maintain the function to control or prevent release of huge amount radioactive material due to trouble or break of reactor facility.
