Newly-discovered radiation levels in one of the Fukushima Daiichi Nuclear Power Plant’s reactors are stunningly high, the Japan Times and others have reported. The space is so radioactive that even a robot couldn’t last two hours, let alone a human.
It was on March 11, 2011, that the coastal power plant in Japan’s Fukushima Prefecture was hit by a tidal wave, which not only cut off the plant’s electrical power, also took out the generators that provided its backup power. The natural disaster triggered the meltdown of three reactors at the plant.
The new readings come from inside reactor two, where the radiation levels are 530 sieverts per hour, according to Tepco, the Tokyo Electric Power Company. That’s highly radioactive— most radiation is measured in thousandths of a sievert, a unit called a millisievert.
