China News Service, November 17th. According to Singapore’s “Lianhe Zaobao” report, the Japanese scientific research team said that a six-year research test showed that the groundwater of Japan’s Fukushima Daiichi Nuclear Power Plant contained tritium, a radioactive substance exceeding the natural standard concentration.
This is the first time that tritium has been continuously detected in the groundwater surrounding the Fukushima Daiichi Nuclear Power Plant.
According to reports, the research team of the University of Tokyo in Japan published the results of this research in the British "Science Report" magazine on the 16th.
According to the research report, during the six years from December 2013 to December 2019, a research team composed of Toda's Environmental Analytical Chemistry Laboratory observed groundwater in 10 places around the Fukushima Nuclear Power Plant and investigated the concentration of radioactive substances such as tritium.
As a result, tritium at an average of 20 becquerels per liter was continuously detected in multiple places.
According to the research team, this is the first time that tritium has been continuously detected in the groundwater surrounding the Fukushima Daiichi Nuclear Power Plant.
According to reports, tritium is also contained in natural rainwater and other substances, but the concentration is less than 1 becquerel.
Team member Katsumi Kozugawa believes that the origin of tritium can only be the Fukushima Daiichi Nuclear Power Plant.
The research team also pointed out that it is necessary to adopt a stricter surveillance system around the site.
