The amount of radiation in the Pacific Ocean is 6 times higher

According to a survey by the Japan Marine Survey, published on March 12, the incident at the Fukushima-1 nuclear power plant in March 2011 caused the content of radioactive cesium in water. Pacific ocean is 6 times higher than previous tests.

Earlier, Representative of Japan Nuclear and Industrial Safety Agency, Mr. Hidehiko Nishiyama said that the high amount of radioactive water leaked from the country's No. 1 Fukushima nuclear plant has flowed directly into the Pacific Ocean. .

This amount of radiation comes from the maintenance pit on the side
outside of nuclear plants adjacent to the sea.

Japanese scientists conducted seawater samples tests at 500 coastal points in Fukushima Prefecture, and concluded that cesium -137 waste from the nuclear power plant was from 4,200 to 5,600 TBq (Bq is The unit measures the intensity of the object's radiation, at 1 Bq, by the intensity of radiation when an object has 1 decay in 1 second). This amount is 6 times higher than previous test results.

Radioactive cesium-137 is extremely dangerous because it can accumulate in the body, destroy muscles and trigger cancer. The half-life of cesium-137 is about 30 years.

The survey also shows that the total amount of radioactive emissions from the "Fukushima-1" plant to the Pacific is about 13-15 thousand TBq.

However, some radioactive substances have a short half-life and are not dangerous to date.
