According to BBC, with reference to the Japanese government, releases of radiation from the nuclear power plant "Fukushima-1" affected by the March 11 earthquake reached levels dangerous to human health.
On this Japanese nuclear power plant on Tuesday night there was a third explosion suffered by the second reactor of the six.
Also Tuesday, there was a release of radiation into the atmosphere during the fire in the pool for spent fuel rods at the fourth reactor of the same station, reported the International Atomic Energy Agency (IAEA). Now, according to the IAEA, the fire was extinguished.
The reactor itself was shut down before the earthquake. The fuel rods are so hot that water boils up in the pool, reports AP.
Cooling System NPP "Fukushima-1" was damaged March 11 earthquake of magnitude 9.0. The representative of the Japanese government informed the Agency France Press, that a slight increase in temperature was recorded at two more reactors.
The accident at the nuclear power plant, built in 1970, has caused concern for the safety of other nuclear facilities in the world. In Germany, Chancellor Angela Merkel gave the order for three months drown seven reactors running until 1980.
Authorities have established an exclusion zone within a radius of 20 km from the station to the evacuation of all residents. Those who live at a distance of 20 to 30 km, it is recommended not to leave their homes.
As the The IAEA, the Japanese authorities were assessed for exposure 150 people, 23 of them required decontamination, reports Reuters.
According to the company's nuclear power plant operator Tokyo Electric Power Co (Tepco), the background radiation in the area of the accident is that if one hour of exposure a person receives a dose of radiation at eight times the annual rate. Previously recorded a sharp jump in, but then again, the radiation level dropped, the representative of the Government of Japan.
Increased radiation recorded in Tokyo, located 250 km from the station, but later on there and its level decreased, France Press reports referring to the mayor's office.
BBC so falls chronicle of events on the "Fukushima-1":
- March 11: the refusal of the cooling system of one of the reactors after the earthquake started evacuation
- March 12: radioactive emerged, hydrogen explosion and partial destruction of the first power
- March 13: failure in the cooling system of another reactor
- March 14: a hydrogen explosion in the third power plant, failure of the cooling system of the second reactor
- March 15 explosion of the second power unit, a fire in the premises of the fourth reactor, a significant increase in the level of radiation
Japanese scientists have tried to stabilize the situation in the second reactor for the entire day on Monday March 14. The immediate cause of the explosion has not yet been established.
On Saturday, March 12 at the hydrogen station exploded in the first power on Monday — in the third. It has been reported that the reactors of the explosions were not injured.
At nuclear power plants continued attempts to restore the cooling system of power: the engineers pumped seawater into the reactors in an attempt to prevent the overheating reactors, however, according to some reports, four out of five water pumps were disabled explosion in the third unit.
The blast, which occurred on Tuesday, could be damaged by an outer protective shell of the second reactor.
Kyodo news agency reported that the Prime Minister of Japan Naoto Kan dissatisfied with the management of the company Tepco.
"The TV reported an explosion. A machine premiere nearly an hour did not report — Agency reporter heard the word premiere at the meeting with the managers of the power company. — What the hell?"
Earlier, Japanese media reported that the water level in the second reactor power down so that part of the fuel cells were exposed.
The explosion on March 14 from the third unit suffered 11 people.
Now, all nuclear power plants in Japan are stopped. Under normal circumstances, they generate a third of the electricity consumed in the country, and the authorities have imposed rolling blackouts and other measures to restrict energaspazhyvannya.
