Iodine 131, cesium 137, plutonium and other substances from the hell of Fukushima

Iodine-131 is just an evil substance that escape, at present, nuclear power plant in Fukushima Daichi 250 kilometers from Tokyo. There is also the very Cesium-137 cancer that attacks muscles and internal organs and remains radioactive for 600 years. O follows the plutonium reactor at the plant using the blended fuel known as MOX.

Named after the Greek god of the underworld, Pluto, its discoverer Glen Seaborg called it "the most dangerous substance on earth." Iodine-131 but will be remembered more than the rest in Ukraine and Belarus and caused 8,358 reported cases of thyroid cancer, most of them children, after the Chernobyl disaster in 1986.

Therefore, it may be significant that, after leaving the light abysmal differences between nuclear authorities in Japan and the USA. States on the levels of radioactivity around the plant, Japanese scientists at Kyoto University on Friday published the results of their own tests for radioactivity, specifically the intensity of Iodine-131 releases.

"There are no published official data on iodine concentration: the government should make public the real information so we can protect ourselves," said Tetsuji Imanaka one of the team that conducted the tests, in an interview yesterday in his office. These internal reviews of independent scientists occur after a U.S.

diagnosis of the disaster that contradicts the Japanese authorities in key areas from the levels of radioactivity were recorded around the plant to be sized to the evacuation zone. EE. UU. advised its citizens living in the area to move further than 80 miles from the plant compared to 20 kilometers advised by the Japanese government.

"The consolation for us is that there are people measuring the radioactivity that are not Employees of the Japanese government," said the Irish writer, based in Tokyo, Eamonn Fingleton, one of the increasingly scarce even peramenece expatriates in Tokyo. Another scientist at the Research Reactor Institute in Osaka, Hiroaki Koide, believes that Tokyo is already contaminated by radioactive materials.

" The most striking example of discrepancies between EE. UU. and Japan, came yesterday when Japanese technicians Tokyo Electric (TEPCO), which manages the plant yesterday denied the claim Jaczo Gregory, president of U.S. regulatory body the Nuclear Research Council that the waste stored at reactor number four had been without water, the possible reason of fire in a waste storage tank on Tuesday.

There is a minor issue. Be true that the call has dried puddle of waste could be imminent catastrophic merger of nuclear waste, an event even more fearsome than the meltdown of a reactor and in the process of generating nuclear energy that is deposited on pools are the most radioactive materials, including Iodine 137.

The explosions last weekend in reactor number four have left a hole in the containment unit as "any waste issue would be addressed directly to the outside," says the Union of Concerned Scientists in the U.S.. UU. To make matters worse, there are indications that the water in the pools of waste five six reactors has dropped to dangerous levels.

Only been three days since the Tokyo Electric technicians believe that these three reactors were out of danger as they were mandatory when the earthquake struck. Now there is the possibility of fusion reactors 1, 2 and 3 and also in the waste tanks 4, 5 and 6. "On Saturday I thought we had repeated Three Mile Island but it was just the beginning of the nightmare," said Imanaka.

A meltdown in a spent fuel pool to would test the resources of the tenacious public relations machine of the nuclear industry has never given a convincing answer to the thorny issue of how to store during the centuries or millennia, so toxic substances. Although we always try. In 2000, while still weighing the memory of Chernobyl, Dixie Lee Ray, then head of the Atomic Energy Commission which brings together the major nuclear energy companies esatdoundses said the waste issue was "the biggest problem is not history ".
