The Japanese Government through the Nuclear Safety Commission has increased the level of nuclear radiation hazards due to damage Fukushima Daiichi nuclear power plant to the highest level, as reported by NHK.
Level seven which is the highest level of nuclear radiation hazard only been established during the Chernobyl disaster in 1986. It (the highest level) is the initial calculation, and the end result will be presented the International Atomic Energy Agency) IAEA)," said an official of Nuclear and Industrial Safety Agency (NISA), reported Reuters.
But the unnamed official said the amount of nuclear radiation that leaks of only a tenth of the Chernobyl tragedy. The decision to increase the level of nuclear radiation risk was made after the radiation of 10,000 terabequerel per hour was detected in the destroyed power plant for several hours.

The condition, according to Radiology and Nuclear Event Scale International (Ines) has entered the category of level seven or the highest level. However, another report stated that a level radiai now decreased to less than one terabequrel per hour.
So far, the level of nuclear radiation risks in Japan set out in the same five levels of radiation levels at the Three Miles Island nuclear plant in the United States leaked in 1979. Besides increasing the level of this radiation, the Japanese government to expand the evacuation zone of plant location due to fears of increased radiation.
Japan Nuclear Commission in accordance hasilm preliminary calculations, the cumulative level of radiation beyond the tolerance limit of 1 milisievert per year at a radius of 60km to the north and 40km to the south of NPP.
Monday (11 / 3) Japan again rocked by an earthquake measuring 7.1 on the Richter scale and caused three deaths and triggering tsunami alarm. In addition, workers who are working to improve the Fukushima Daiichi nuclear power plant was forced to evacuate.
Fukushima Daiichi nuclear power plant cooling systems destroyed by the earthquake and tsunami that struck Japan last month. Workers are now attempting to control the temperature of a nuclear reactor at the nuclear power plant.
Besides damaging Fukushima nuclear power plant, the earthquake and tsunami left more than 28,000 people dead or missing and 150,000 currently a refugee.
