Japan told the United Nations atomic agency that 28 workers were exposed to high doses of radiation during work to stabilize the troubled nuclear plant in Fukushima Daiichi. Of the 300 people on the ground shaking a month ago by an earthquake and tsunami, 28 accumulated dose above 100 mSv (mSv), said on Friday the International Atomic Energy Agency (IAEA, for its acronym in English), citing data Japanese authorities.
"No worker received doses above 250 mSv, the guideline value of Japan to restrict the exposure of emergency workers," said Vienna-based agency. The average dose to a nuclear plant worker receives over five years is 50 mSv. Two workers at the plant in Fukushima were taken to hospital last month after his feet were exposed to between 170 and 180 mSv after stepping on contaminated water.
Both have recovered. Fukushima was the worst nuclear accident since Chernobyl, 25 years ago. The Japanese authorities have rated the highest score on an international scale for such disasters. However, unlike Chernobyl, nobody seems to have died from radiation.
