The enterprise went through inspection in October

The Federal Service for Ecological, Technological and Nuclear Supervision (Rostekhnadzor) reports the violations which would indicate the isotope ruthenium leakage were not found in the Mayak operation.

According to the Rostekhnadzor press service, the enterprise verification was being completed in late October and early November. The reason for the verification was information on the recorded increase in the ruthenium-106 concentration in the atmosphere over several European countries. The Federal Service claims the specific activity of radionuclides in the surface air, including the specific activity of the ruthenium-106 isotope, did not exceed the permissible and control levels in the territory of the enterprise and in the adjacent territory from August till October.

Besides, the inspectors did not find any irregularities in the operation of the equipment that could have caused the radioactive material leakage.

Meanwhile, Rosatom said the corporation is ready to assist state structures and public organizations «to establish the true causes of increasing ruthenium concentrations» in the atmosphere. Specialists from the corporation explained that the amount of the isotope manufactured in 2017 by Russian suppliers for the medicine needs is not enough to cause a fixed level of air pollution.

«The source of the radioactive isotope could be, for example, the furnace of a plant for the processing of ferrous and non-ferrous metals. Since we do not have data on the time of the beginning of the isotope propagation, we can only calculate approximately where it flew from. It has no reason to guess and calculate the trajectories now. The volume of radioactive ruthenium-106 detected by Roshydromet in the Chelyabinsk region is several million times less than the dangerous values. The important thing is that there is no danger to people», — Leonid Bolshov, Scientific Supervisor of the Nuclear Safety Institute of the Russian Academy of Sciences, explained.

Let’s remind, Roshydromet published a report before, which contains information on the increase in the isotope of ruthenium concentration in the atmosphere recorded on the territory of the Russian Federation. The authorities of Germany and France announced an increase in the ruthenium isotope concentration in the atmosphere over the European countries. Scientists from the Radioprotection and Nuclear Safety Institute (IRSN, France) published a map compiled on the information from control and weather stations basis. According to the IRSN calculations, the source of the isotope leak could be located on the territory of the Russian Federation.
