A possibility was, however, rejected by a spokesman for the Russian nuclear energy operator Rosenergoatom, which guaranteed, in statements to the news agency Tass, no problems have been reported.
The Leningrad power station, near São Petersburg, and Kola, near the city of Murmansk, in the north, “are operating normally, with radiation levels within the norms,” he added.
Finnish, Norwegian and Swedish nuclear security watchers said this week they had detected small amounts of isotopes radioactive harmless to humans and the environment in parts of the Finlândia, southern Scandinavia and the Arctic.
The Swedish Radiological Safety Authority said on Tuesday that it was not possible for now to “confirm the source of the increased levels” or the origin of a cloud containing isotopes radioactive that will be over the skies of northern Europe.
The Finnish and Norwegian authorities have also not speculated on the possible source of the changed levels of radioactivity, but the Dutch National Institute of Public Health and Environment said on Friday that data show that “the radionuclides (isotopes radioactive) comes from direction of western Russia “.
“The radionuclides they are artificial, that is, they were created by humans. The composition of nuclides it can indicate damage to a fuel element in a nuclear power plant “, said the Dutch organism, adding that” the specific origin cannot be identified due to the limited number of measurements “.
The executive secretary of the Nuclear Test Ban Treaty Organization, Lassina Zerbo, stated, in a message released on Friday through Twitter, that monitoring radiation organization in Sweden detetaram a slight increase in several harmless isotopes in the airspace of northwest Europe.
The spokesman for the Russian operator Rosenergoatom, which was not identified in the news released today by Tass, ensured that the radiation levels of the Leningrad and Kola plants and areas adjacent areas “remained unchanged in June“and that” no changes have been observed so far “.
“The two centers are working in a normal regime. There were no complaints about the performance of the equipment,” said the same source, adding that “no incidents of radionuclides out of the containment structures “.
