Experts: Radioactive water spread out over the ocean for 3 months

French Institute for Nuclear Safety calls for long-term monitoring of the Pacific Ocean off the north-eastern coast of Japan following the radiation leak from the nuclear power plant "Fukushima-1", reports NHK.

Institute for Radiological Protection and Nuclear Safety, analyzed the impact of the sea by the recent leak of water with high levels of radiation from the reactor number 2. Computer analysis was based on publicly available data.

The analysis showed that as of Monday water contaminated with radioactive substances, spread over areas off the coast of Fukushima and Miyagi prefectures.

The analysis also revealed that the airborne radioactive material mixed with sea water. Research predicts that the contaminated water can spread over the Pacific Ocean for three months by the Japan Current.

French Research Institute said that some of the radioactive substances can be dissolved in sea water, and the other with a high degree of probability can settle on the seabed.

The researchers added that the cesium-134 can remain in the sea for several years, and cesium-137 — for 30 years. French warn that fish and seaweed in the Pacific coastal waters of Japan may be contaminated with these radioactive materials.

As reported by "Rosbalt", the content of the radioactive isotope of iodine is now near the water inlet of the second reactor nuclear power plant "Fukushima-1" decreased significantly, but higher than the marginal rate of 140 thousand times. According to the statement, the figure at the beginning of the week exceeded 7.5 million times in Japan set the marginal rate in the water that poured into the Pacific Ocean from the 2nd NPP. Such a result is an analysis of the samples taken in the area of the southern intakes April 2. At that time, the concentration of iodine-131 per cubic centimeter of water was 300 thousand becquerels.

Now, however, said the representative of the energy company, the level of radiation near the plant from the ocean dropped significantly. This has been accomplished professionals morning of 6 April, after blocking the uncontrolled leakage of highly radioactive water from the well of technical associated with drainage station.

Recall March 11 earthquake of magnitude 9 points was the most devastating for the entire postwar history of Japan, beating the number killed the sad record of the Kobe earthquake in 1995. Ensuing tsunami destroyed infrastructure north-eastern Japan, and destroyed the cooling system of reactors at the plant "Fukushima-1". On the 1st, 3rd, and possibly 4th NPP units in the first days of the accident there were powerful hydrogen explosions. They inflicted great damage to these buildings, have led to the spread of radioactive debris.
