Much attention is currently limited to about fifty technicians, engineers, workers and firefighters, who sent the operator of nuclear power plant Fukushima almost as a last resort to the reactor site and in the building to avoid the worst: the melting of the reactor core and release by even larger amounts of radioactive particles.
Packed in bright full body suits and equipped with masks, some also with air tanks on their backs, from which they are supplied in highly contaminated areas with air, the men go to their work. When measured after a steam explosion in some places of the reactor site peaks of more than 400 mSv per hour - or about four thousand of the total radiation X-rays - the workers had to temporarily leave the location altogether.
Dangerous for the workers primarily volatile radionuclides such as cesium 137, which emits gamma rays in nuclear decay. These short-wave-energy rays act almost like X-rays: They penetrate almost freely clothing - the clothing of the power plant workers - and destroy their way through the body, especially the genetic material of cells that have to share quickly, such as blood cells and mucous cells.
Five hours of continuous work in the most contaminated areas reactor would be virtually a death sentence. A first list of victims was the operating company Tepco submitted to the International Atomic Energy Agency on Thursday: they share after the explosions in various reactor blocks, two workers missing, fifteen employees were injured, and it should be, by six employees of the operating company Tepco, five of subsidiaries on the premises and four technical experts of the Japanese aid organization.
To contamination, the company announced that observed in seventeen people were radioactive particles on the face, but which were not treated further in the hospital. Two police officers were decontaminated and an undisclosed number of firefighters was "under observation". A single worker was exposed, therefore while "venting works" higher radiation doses. Important information about the received radiation dose should be especially Ganzkörperdosimeter carrying the men during their work.
