In recent weeks, radiation levels have spiked at the Fukushima nuclear power reactors in Japan, with recorded levels of 10,000 millisieverts per hour (mSv/hr) at one spot. This is the number reported by the reactor's discredited owner, Tokyo Electric Power Co., although that number is simply as high as the Geiger counters go. In other words, the radiation levels are literally off the charts. Exposure to 10,000 millisieverts for even a brief time would be fatal, with death occurring within weeks.
