According to reports, a seriously injured worker was trapped within Fukushima Daiichi unit 1 in the crane operating console of the exhaust stack and is now confirmed to have died. Four workers were injured by the explosion at the same reactor and have been taken to hospital. A contractor was found unconscious and taken to hospital. Two workers of a 'cooperative firm' were injured, said Tepco; one with a broken bone. At Fukushima Daiini unit 3 one worker received a radiation dose of 106 mSv. However, given the high levels of radiation inside the plant, and the opacity of information about what has actually gotten out, it is difficult to speculate at present on the true extent of radioactive contamination in the immediate and surrounding areas near the plant.
