UN panel says Japan nuclear workers may have got higher radiation

Japanese authorities may have underestimated by 20 percent the radiation doses workers got in the initial phase of the Fukushima nuclear power plant disaster, a Japanese newspaper reported on Saturday, citing a UN panel.

A big earthquake and tsunami in March 2011 damaged the power station north of Tokyo, operated by Tokyo Electric Power Co, causing three partial reactor meltdowns. The company has struggled to contain leaking radiation since then. (Reuters)
