Workers exposed to nuclear leak at stricken Fukushima plant

The operator of Japan’s crippled nuclear power plant says six workers have been exposed to highly radioactive water that poured out of a treatment unit when they removed a pipe.
Tokyo Electric Power (Tepco) said exposure to the Fukushima workers, who were wearing face masks and protective gear, is believed to be minor but is still under investigation. It is believed the wrong pipe was removed.
