Radiation levels in Fukushima Daiichi Reactor 3 more than doubled in many locations since measured last year
TEPCO announced that the robot used to enter the Fukushima Daiichi Unit 3 Reactor Building measured radiation levels up to 4,780 mSv per hour, nearly three times the 1,300 mSv reading taking in the same location last year on November 14th, 2011. [...]
[...] TEPCO did not state the nature of the inspection other than to look at the gas duct hose. It appears the concern was due to increasing radiation levels in the area. TEPCO was likely inspecting the duct as the source of the possible increase. No leaks or damage were found on the duct.
What they found was that the containment door and track were the source of the increased radiation levels. [...]
The first graphic [on right] is the levels for the containment hatch and rail. Levels from 2011 are included to compare to the new levels showing the increase.
