The NFRDI announced results of surveys on seawater in Korea conducted in conjunction with the KINS.
Surveys identified that seas in Korea are safe from radioactivity.
The National Fisheries Research & Development Institute (NFRDI) and Korea Institute of Nuclear Safety (KINS) said on August 27 that surveys on seawater in coastal areas of Korea found that water contaminated by radioactivity of the nuclear power plant in Japan has not flowed into seas in Korea thus far. In order to find out impact of the radiation leakage accident occurred at the nuclear power plant in Fukushima, Japan on fishing grounds and marine creatures in Korea, these organizations have been conducting surveys on seawater in Korea since 2011.
Since January 2011, the NFRDI has collected seawater at 75 places in the East Sea, West Sea, South Sea and East China Sea in every two months, and sent samples to the KINS for detection of radioactivity.
Surveys on radioactivity conducted for 3 years identified that water contaminated by radioactivity leaked from the nuclear power plant in Fukushima did not affect seawater in Korea, as radioactive iodine (131I) and radioactive cesium (134Cs) were not detected, and trace of radioactive cesium (137Cs) was detected on the same level as before the radiation leakage accident occurred.
While concerns over leakage of contaminated water from the nuclear power plant in Fukushima is increasing, the NFRDI predicts that its actual impact on Korea will be insignificant because the contaminated water will take about 5 years to reach Korean peninsula after circulating around the world riding the ocean current and radioactivity will be diluted in this course.
But the NFRDI said it will continuously monitor changes in ocean current and structure of seawater in preparation for any unexpected situation.
In early September, the NFRDI will collect seawater in the East China Sea to analyze radioactivity in ocean current flowing into seas in Korea, and it will regularly conduct radiological monitoring activities in coastal areas of Korea once a month.
President Jeong Yeong-hun of NFRDI said, “The Institute will intensify monitoring activities in coastal areas of Korea and expand cooperation with related organizations in Korea and other countries so that the people can be relieved.”
