Six years after the tsunami that destroyed it, the Fukushima nuclear reactor is still throwing off huge amounts of radiation. And yet people who lived nearby may soon return to their homes and businesses.
The UK Independent reported that radiation levels are still so high at the plant that robots are burning out far more quickly than imagined:
The latest attempt to harvest data on Fukushima failed after a robot designed by Toshiba to withstand high radiation levels died five times faster than expected.
The robot was supposed to be able to cope with 73 sieverts of radiation, but the radiation level inside the reactor was recently recorded at 530 sieverts.
A single dose of one sievert is enough to cause radiation sickness and nausea; 5 sieverts would kill half those exposed to it within a month, and a single dose of 10 sieverts would prove fatal within weeks.
