"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 U.N. panel."
"A big earthquake and tsunami in March 2011 damaged the power station north of Tokyo, operated by Tokyo Electric Power Co. (TEPCO), causing three partial reactor meltdowns. The company has struggled to contain leaking radiation since then.
The U.N. Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) raised doubts about the dose estimates of the government and TEPCO, in a summary of a report on Oct. 12, according to The Asahi Shimbun Japanese newspaper.
The U.N. committee analyzed radiation doses in 25,000 people who worked at the plant on or before October 2012, using data provided by the government, TEPCO and others, the newspaper said."
