The accident Fukushima ranked on a par with Chernobyl

The Japanese Nuclear Safety Agency has high Tuesday, April 12, accident nuclear power plant in Fukushima-1 at the maximum level of 7 on the scale of nuclear and radiological events (INES), placing the same degree of seriousness the Chernobyl disaster. However, she warned that the level of radioactive emissions since the beginning of the nuclear accident achieve only 10% of that measured in 1986 after the disaster at the plant located in Ukraine.

"We have not regretted the same irradiation of people. There have been releases in Fukushima vapors and fumes, but not of the same or similar magnitude as Chernobyl has highlighted a spokesman Agency. Japanese nuclear authorities still fear that the "radioactive leaks" do not "eventually exceed those of Chernobyl.

Proof of the seriousness of the situation, traces of strontium, a highly radioactive element produced by nuclear fission, have been found for the first time in soils and plants near the central An official at the Japanese Agency for Safety Nuclear stressed that the decision to reconsider the severity of the accident to the increase had been taken "on the basis of measurements of iodine and cesium found in the environment." "We will continue to monitor the situation.

It is an interim level, "he said, adding that the final decision to classify the accident at 7 would be taken later by a committee of international experts. So far, the Japan ranked at the accident 5, which corresponds to an "accident-reaching consequences", while his French counterpart to the estimated 6, the level of a "serious accident".

Level 7, the most important is a "major accident . Only the Chernobyl disaster has been declared so far to the maximum degree, meaning that a "major release of radioactive material" was produced with "significant effects on health and the environment." Despite this decision, the Prime Minister of Japan, Naoto Kan, wanted to show reassuring, saying the situation "stabilizes step by step" and that the radioactive leaks down.

Asked about the apparent contradiction between his remarks and the decision to elevate Level 7 of gravity of the accident in Fukushima, Mr Kan said: "We have reassessed the level on the basis of an assessment of the extent of radioactive emissions can be high." He also assured that "the health of citizens is the guiding principle of government decisions ", asking the Japanese to" resume normal life "and eat after the holding period they are imposed.

Meanwhile, the aftershocks of the devastating earthquake on March 11 continued to shake the northeast coast of Japan. A strong earthquake of 6.3 magnitude occurred, early Tuesday afternoon in the area of Fukushima. Its hypocenter was located only 10 km deep. Employees of the Central Fukushima-1 were evacuated as a precaution.

TEPCO has ensured that its electric pumps continued to operate normally for cooling nuclear reactors. Experts say repeated earthquakes could cause additional damage to already severely damaged the plant.
