Fukushima Daiichi: Robots measure high dosage levels in Unit 1 and 3 reactor buildings

Sunday and Monday robots measured radiation dosage levels in Unit 1 and 3 reactor buildings.

Unit 1

TEPCO said the robots surveyed the first floor of Unit 1 for about 50 minutes.

The maximum radiation reading reported was 49 mSv/hr.

Unit 3

TEPCO said a robot attempted to survey inside Unit 3 for about 2 hours, but apparently debris restricted its movements.

The maximum radiation reading reported was 57 mSv/hr.

The maximum permissible dose for Japanese nuclear workers was 100 mSv per year before the accident at Fukushima Daiichi. Shortly after the accident, the Japanese government increased the annual limit to 250 mSv for emergency situations. The World Health Organization considers 500 mSv/year acceptable for emergency work.
