Radiation dose measurements from the Fukushima Daiichi Nuclear Power Station Unit 1 Reactor Building Torus Room, 26 June 2012. The maximum reading was 10,300 millisieverts/hour before the dosimeter failed. TEPCO

28 June 2012 TEPCO, soon to be “effectively” nationalized, sent own workers to the Reactor 1 building at Fukushima I Nuclear Power Plant on June 26 to measure the water level, radiation levels and temperatures inside the Torus Room. The workers used the CCD camera fitted with thermometer and dosimeter, and fed the cable through the gap in the floor from the 1st floor of the reactor building. Right near the surface of the water, it was 10,300 millisieverts/hour, or 10.3 sieverts/hour. TEPCO reports that the dosimeter failed in the water, at it exhibited the values of “10^8 – 10^9” (100,000,000 to 1,000,000,000) millisieverts/hour. If you recall, this was the reactor building where the steam measuring 4 sieverts/hour was gushing through the gap between the pipe and the floor on the first floor. From TEPCO’s Photos and Videos Library, June 27, 2012 (there is also a 40-minute video, I’ll post here later): […]
