Radioactive substances found over Northern Europe. Activists suggest that the release occurred due to damage to the reactor or fuel cell of an atomic icebreaker, nuclear submarine or depressurization of spent nuclear fuel in Russia.
Greenpeace activists found a slight increase in the concentration of artificial radioactive substances in the air over Europe. They suggested that this was due to harmful emissions in western Russia. This information was confirmed by the Swedish, Norwegian, and Finnish radiation protection authorities.
We are talking about several substances at once: Iodine-131 was found in Norway, and cesium-134, cesium-137, cobalt-60, and ruthenium-103 – in Sweden and Finland. All of these radionuclides are of reactor origin. Activists emphasize that the concentration of substances is extremely low. Experts note that judging by the composition, we are talking about damage to the primary circuit of a reactor or fuel cell at a nuclear power plant. Other versions of experts are that such contamination is possible if the reactor or fuel cell of an atomic icebreaker, a nuclear submarine is damaged, or spent nuclear fuel is depressurized.
The Dutch National Institute for Public Health and the Environment (RIVM) performed more detailed calculations to find out the origin of the substances found. According to them, radionuclides come from the west of Russia. But they could not establish the specific location of the leak.
Experts from the Netherlands suggest that the leak could have occurred at the Kola NPP or on the basis of the nuclear fleet of the Northern Fleet, which are located on the coast of the Barents Sea. In addition, this leak could occur at three operating reactors of the Leningrad NPP.
