Fukushima News: 'Unimaginable' Nuclear Reactor Radiation So Destructive, Not Even Robots Can Survive

Radiation inside Japan's Fukushima nuclear plant reached such astronomical levels Thursday that not even a robot could survive inside. A remote controlled cleaning machine sent into the incapacitated plant had to be pulled out after it ceased to function due to high levels of radiation. It was the first time a robot had entered the No. 2 reactor since the plant's meltdown in 2011. Radiation reached "unimaginable" levels recently, experts told The Japan Times. The previous high was measured at 73 sieverts per hour, one year after the disaster.
