Japanese academic: A hard look at the true impact of Fukushima Daiichi water release

By Koji Okamoto 16 May 2023
Amid protests by Japan's neighbours, China and South Korea, as well as by environmentalists about Japan's impending release of treated water from the Fukushima Daiichi plant, Japanese academic Koji Okamoto explains that the radioactive substance “tritrium” present in the treated water to be released is naturally present in the environment. In fact, the release of the treated water is of negligible impact compared to the originally present tritium or tritium being released in currently operational nuclear power plants around the world.
