Roshydromet's data on isotope contamination with ruthenium-106 allow us to conclude that the dose that could have been received by a person is 20 thousand times less than the maximum permissible annual dose and does not pose any danger to human health and life.
The first data on the increased values of the volume activity of Ru-106 in the atmosphere was recorded simultaneously in the countries of Western Europe, in Tatarstan, Volgograd and the Southern Urals at the same levels (10-20 mBq / m3). Extremely high concentrations of Ru-106 in the atmosphere were recorded in Slovakia (29-30.09.2017) and in Romania (September 30, 2017), which are located at a distance of about 3,000 km from FSUE “Mayak Production Association”.
The atmospheric pollution by the isotope Ruthenium-106, indicated in the report of Roshydromet, is not related to the activities of the FSUE Mayak Production Association.
Ruthenium-106 can enter the atmosphere in the following cases:
In 2017, there was no production of the ruthenium-106 sources at FSUE “Mayak Production Association”, emissions to the atmosphere were in the usual regulatory values. Radiation background is normal.
We additionally inform that we haven’t done the separation of ruthenium-106 from the spent nuclear fuel (and have not produced on its basis the sources of ionizing radiation) in our company for many years now."
Thus, FSUE “Mayak Production Association” is not a source of the increased ruthenium-106 content in the atmosphere.
Head of Roshydromet: The published data does not allow us to establish the location (country) of the pollution source
"Recently, the media have been reporting more frequently on the concentration of ruthenium-106 on the territory of Russia and abroad. In this regard, I would like to underline once again that at the end of September the automatic monitoring system recorded an increased content of ruthenium-106 not only in Russia, but also on the territory of other countries including Poland, Bulgaria, and Romania. At the same time, the concentration recorded was at a level of thousands of times lower than permissible values. For comparison, the concentration of ruthenium in Romania was 1.5-2 times higher than in Russia; in Ukraine and Poland the concentration was comparable to that in Russia. There was no concentration higher than permissible levels, and it does not pose any danger to the population. The published data does not allow us to establish the location (country) of the pollution source", states the Head of Roshydromet Maxim Yakovlenko.
