Gamma views, between Fukushima Daiichi No.1 and No T-Shirt

In August 2011, at the bottom of the main exhaust ventilation system located between No. 1 and No. 2 reactor buildings at the Fukushima Daiichi Nuclear Power Plant, the radiation dose of 10,000 millisieverts (10 Sieverts) or more per hour after the accident was measured. A person can die from bone marrow dysfunction if he is exposed to more than 4,000 millisieverts (4 sieverts) at a time. Gamma Camera (Gamma View) is a color change that shows the relative intensity of radiation, like thermography, and increases the intensity of radiation as it changes to blue, green, and red.
