#Fukushima I Nuke Plant Reactor 3: Radiation Went UP After Packbots Cleaned the Guide Rail to CV, EX-SKF, Nov. 23, 2011:
After 2 Packbots wiped the guide rail to the Containment Vessel hatch on the 1st floor of Reactor 3, they were sent back in to measure the result of their operation in terms of radiation levels.
Well, the levels may have gone up. As you can see in the handout for the press on November 22, 2011, after the cleaning operation the measurement by the survey meter fluctuated so much that TEPCO couldn’t put down the single number for each location. [...]
For example, before ‘cleaning’ at point 3 the radiation dose was 750 mSv/h, after cleaning it ‘fluctuated significantly’ between 750-1,600 mSv/h.
