Japan maximizes the nuclear event scale

Japan raised the severity of their nuclear crisis in the Fukushima Daiichi power plant, at 7 from 5, being on par with the Chernobyl nuclear disaster in 1986. The rating reflects the initial severity of the crisis and not the current situation, in which radiation levels have fallen dramatically. "This is a preliminary assessment and is subject to the completion of the International Atomic Energy Agency (IAEA) "said an official of the Agency for Nuclear and Industrial Safety (NISA, for its acronym in English), the atomic monitoring agency in Japan, which made the announcement along with the Nuclear Safety Commission.

However, the agency noted that the radioactive emissions from the plant in Fukushima are 10% of which were released during the Chernobyl accident, which occurred when the reactor was operating at full capacity, while in Japan the operations were stopped by the earthquake. Japan struggles to regain control of Fukushima Daiichi plant after the earthquake and tsunami earthquake that devastated the North East on 11 March.

Scale International Nuclear and Radiological Event Scale (INES) is published by the IAEA and classifies accidents and nuclear and radiological incidents by severity from 1 to a maximum of 7. The increased severity of the accident at the international level is based on provisional estimates of the Japanese Nuclear Safety Agency, which has detected high concentrations of cesium and radioactive iodine in the area.

"We have increased the severity level to 7 because the impact of radiation leaks has been widespread in the air, plants, drinking water and the ocean, "said Minoru Oogoda Japanese agency. The NISA authorities said another factor in which the decision was based was that the total amount of radioactive particles released into the atmosphere since the tsunami struck the plant have reached levels equivalent to a level 7 incident.

Two new aftershocks shook Japan in and later discovered a fire at the Fukushima nuclear plant was quickly extinguished. The first reply of 7.0 magnitude, occurred just hours after the Japanese undertake mourning ceremonies to celebrate a month of the earthquake and tsunami that killed nearly 25 thousand people.

A second replication of 6.3 jolted Tokyo and its surroundings.
