Since the start of the release of treated water accumulated at TEPCO's Fukushima Daiichi Nuclear Power Station, the Ministry of the Environment has been monitoring seawater once a week, and announced that tritium concentrations at all locations have fallen below the detectable minimum limit for the fourth time, as in the past.
The Ministry of the Environment monitors seawater once a week after the discharge of treated water accumulated at TEPCO's Fukushima Daiichi Nuclear Power Station into the sea.
In the fourth session, seawater was collected from 4 to 40 this month at a total of 11 points off the coast of Fukushima Prefecture, including near water outlets and about 13 kilometers away, and the concentration of tritium and other substances was analyzed at a research institute.
The Ministry of the Environment announced on the 15st that the concentration of tritium at all 21 sites was below the lower limit of 11 becquerels per liter that could be detected.
The results are the same: the first on August 1, the second on September 10, and the third on September 8.
The Ministry of the Environment will continue to monitor the event once a week for the time being, and will announce the results on its website and SNS.
