This image shows two spots at the Fukushima nuclear power plant in Japan, at the bottom of a ventilation stack between the No.1 and No.2 reactors, where radiation levels are still high enough to kill a human being. I'm talking about the quick-death-by-radiation-poisoning sort of "kill," not the possible-death-by-cancer-at-some-point-in-the-future sort. At the colored spots, radiation levels were measured at 10 sieverts (10,000 millisieverts) per hour.
The image was captured using a gamma ray camera, the same sort of equipment that researchers use to track radioactive isotopes in the human body as part of medical treatments.
