Normal radiation dose rates at the Fukushima I site as established by the stream of monitoring post readings in the 3 months preceding the accident. (03/01=1 March 2011, 1 Gray= 1 Sv for gamma radiation) [98] Radiation fluctuated widely on the site after the tsunami and often correlated to fires and explosions on site.
On 15 June 2012 TEPCO reported that a robot that was sent into the No. 2 reactor building on 13 June 2012 to take video images and radiation measurements, detected a reading of 880mSv (millisieverts) per hour of radiation on the fifth floor, which one floor (4.5 meters) directly above the reactor containment vessel.

Images taken by miniature drones from deep inside a badly damaged reactor at the Fukushima nuclear plant show displaced control equipment and misshapen materials but leave many questions ...
The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan, which began on 11 March 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami , which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy ...
The Fukushima prefectural government reported radiation dose rates at the plant reaching 1.015 m Sv/h. [59] The IAEA stated on 13 March that four workers had been injured by the explosion at the Unit 1 reactor, and that three injuries were reported in other incidents at the site. They also reported one worker was exposed to higher-than-normal ...
TEPCO claimed no significant change in radiation levels, and the smoke subsided later the same day. [40] On 23 March, black smoke billowed from Unit 3, prompting another evacuation of workers from the plant, though Tokyo Electric Power Co. officials said there had been no corresponding spike in radiation at the plant.
The Fukushima workers had to be wary of radiation spiking—a sudden and unforeseen rise in radiation. [28] This threat forced the workers to evacuate for a short period of time on the morning of Tuesday 15 March 2011 when radiation detected at Fukushima rose to approximately 1000 mSv/h, [ 29 ] the highest level of radiation detected at any ...
