Fukushima workers were exposed to small amounts of radiation Monday while conducting cleanup work at the nuclear power plant. Officials said they're still investigating how workers were contaminated at the Fukushima Dai-ichi nuclear power plant.
Ten workers at Japan's crippled nuclear plant were exposed Monday to small amounts of radiation while conducting cleanup activities, the plant's operator said.
It said small amounts of radiation were found on the workers' faces and hair.
A powerful earthquake and tsunami destroyed power and cooling systems at the plant in March 2011, causing the release of large amounts of radiation. Makeshift equipment is being used to cool the reactors, and the plant has been plagued by blackouts and leaks of contaminated water.
