Three people died instantly while the other 450 were exposed to radiation (119 so severe). On Thursday morning, authorities reveal that , due to a leak of uranium , it triggered an uncontrolled nuclear fission in the reactor core . At 10:30 am the alarm goes off , some workers were contaminated so very serious. At 24:41 the police create a ' cordon ' around the plant , it is understood that the incident is becoming more serious than expected . At 15:18 some families living near the plant are evacuated. 21:00 held an emergency meeting and the government at this point includes the severity of the accident ; over 300,000 people invited to stay at home . 24:00 radioactivity in and around the plant reached levels between 10 and 20 thousand times higher than normal . At 02:30 the following day the plant operates 18 technicians accept a mission by real ' kamikaze ' , they must enter the plant to stop the chain reaction, well aware that , after the mission , would no longer be the same. 06:00 The authorities claim that radioactivity is reduced to zero (0). After it is established that it was a human error , the engineers were in fact carrying, inside the building where uranium is used as fuel in the nearby nuclear power plant, two barrels of uranium - nitric acid mixture (which were mixed in hand , with a rudimentary funnel , 30 kg each : these are unwittingly fallen earth and having mixed, have triggered the reaction. engineers have stopped the reaction to the hospital in critical condition.

1999 October 27 , USA. ' The U.S. children living near nuclear power plants in New York , New Jersey and Florida have in the teeth a ' radioisotope ' ( Strontium 90) that exposes them to a very high cancer risk ' . So Ernest Sternglass , a professor of radiology at the University of Pittsburgh began in the last press conference of the non-profit project of ' radiation protection and public health ' . The disconcerting result was achieved by U.S. researchers who analyzed 515 children residing in the states of New York, New Jersey and Florida. The levels of radioactivity in the samples collected from 1979 to 1992 , they were very close to those seen in the mid- 50s when the United States and the Soviet Union during the Cold War , dabbled in experiments with invisible weapons . According to the project managers levels of radioactivity were intended to be dropped close to zero . ' If the nuclear tests of both surface and underground are actually completed, the first suspicions fall on nuclear reactors and related accidents ' , said Sternglass , who added: ' The world is too small for nuclear accidents ' . The project attribute part of this radioactivity disaster occurred in 1979 at Three Mile Island and Chernobyl in 1986. There are federal documents that testify to escape from the nuclear reactor in Suffolk (New York) in the early '80s .

2004 Aug. 9, Japan. In the No. 3 reactor of Mihama plant , 350 kilometers west of Tokyo, a leakage of steam at high pressure , with temperatures exceeding 200 degrees , it's claimed the lives of four (4) workers. Seven other workers are in very serious condition . It was the most tragic incident in the history of the exploitation of nuclear energy for civilian purposes in Japan. The Kansai Electric Power Company , which operates the plant , was quick to announce that : ' There was no radioactive contamination ! ' .

2004 Aug. 9, Japan. other central unspecified . As far as the agency Kyodo reported , the flames erupted in the area where the waste is disposed adjacent to the reactor number 2 at a plant located in the prefecture of Shimane . Also in this case there was no radioactive leak ...

2004 Aug. 9, Japan. Accident in the nuclear power plant of Tokyo Electric Power Company ( TEPCO ) , the largest producer of energy in Japan. The company announced that the generator plant in Fukushima - Daini was stopped for a loss of water .
