Fukushima Worker Dose Experience Two workers at the troubled Fukushima Daiichi nuclear power plant may have been exposed to high levels of radiation exceeding the safety limit set by the government. If confirmed, these are the first cases of radiation exposure since the health ministry raised the limit in March following the accident. Two […]
