Radiation levels near Japan's damaged Fukushima reactor hit two-year high
TOKYO (REUTERS) - Radiation levels in seawater just outside one of the damaged Fukushima reactors spiked this week to the highest level in two years, the operator of the crippled Japanese nuclear plant said on Thursday.
Radiation levels on Wednesday, the day six workers were exposed to highly radioactive water, jumped 13 times the previous day's reading, the highest levels since late 2011.
A massive quake and tsunami hit the power station, operated by Tokyo Electric Power Co, also known as Tepco, in March 2011, causing three reactor meltdowns and hydrogen explosions.
Tepco, which is pouring hundreds of tonnes of water to keep reactors cool, has struggled to contain the build up of radioactive water at the plant.
