The latter reported that at the end of September was observed extremely high air pollution radioactive isotope ruthenium-106. Exceedances recorded in the southern Urals, Tatarstan, the Volga region and Rostov-on-don.

In the samples of all the posts in the southern Urals have discovered the isotope Ru-106 (half-life 368,2 day).

It is reported that the content of ruthenium in the sample and the observational points of Argayash and Novogornyy exceeded the background in the previous month and 986 440 times. This corresponds to the level of «extreme pollution».

In addition, in late September, the decay products of the radioisotope is detected in Tatarstan, Volgograd and Rostov-on-don.

Following that, from 29 September to 3 October, the content of ruthenium-106 found all European countries, starting with Italy and further North in Europe, said the Roshydromet.

Earlier, the German office for radiation protection recorded in Europe traces of a radioactive substance in a safe for the population concentration.

The office suggested that the source is allegedly in Russia, the southern Urals, without specifying, on the basis of which to make such conclusions. The laboratory of Russian regions said they did not record the last time the air content of ruthenium-106.

This substance is used as a radiation source for procedures for the treatment of cancer. Less frequently it is used in radioisotope thermoelectric generators, which are used in the satellite. It can also occur in the processing of nuclear fuel elements.

The Plant «Mayak»

According to Greenpeace, in the report of Roshydromet in September indicated that the most significant concentration of ruthenium-106 found near the plant «Mayak», where the processed spent nuclear fuel. It is located in the city of Ozersk, Chelyabinsk region

In turn, the company said that the possible pollution of the atmosphere isotope is not related to their activities.

«Additionally, we inform that for the separation of ruthenium-106 from the spent nuclear fuel (and manufacture on the basis of sources of ionizing radiation) in our company are not held for many years», — stated in the message.

As later stated in the «Rosatom» on the Russian objects of nuclear industry, there was no incidents and accidents, which could lead to increased levels of radioactive substances in the atmosphere.

The level of non-hazardous

In turn, the authorities of Chelyabinsk said that the Rosgidromettsentrom reported elevated radiation levels in September.

As stated by the Minister of public security of the region Evgeny Savchenko, the Ministry should warn of the dangerous races of the radiation level. This is to protect the population in case of emergency.

The meteorologist answered that the recorded fluctuations of background radiation, but the level is nowhere near the threat, said Savchenko.

He drew attention to the fact that the sources which disseminated information about radiation were in France, where it is competing with the «Mayak» enterprise for the processing of nuclear waste.

In October the Deputy Governor of the region Oleg Klimov explained that during the processing of spent nuclear fuel ruthenium selected always contains impurities of other radioactive elements, and «pure» EN-106 can only appear during operation of the accelerators or cyclotrons.

In this form it was fixed instruments in Europe, the ruthenium is used for medical purposes or as a reference source when testing devices for radiation control for satellites.

«No threat»

Then said the latter, agencies do not seek the reason of increasing the level of ruthenium-106 in the atmosphere.

According to the head Minister Maxim Yakovenko, the recorded values were a thousand times smaller than the maximum permissible concentration.

«There is no danger», he concluded.

This is also the opinion of the Deputy Director for science of the Institute of industrial ecology Ural branch of RAS Ilya Yarmoshenko.

According to him, the concentration of ruthenium-106 is a no-brainer for people living in this and neighboring regions.

Yarmoshenko said that it is permissible for the security of the concentration of ruthenium is about 4.4 becquerels per cubic meter in the monitoring data it is a hundred times less.

«Of course, the evacuation of the people in this case is not necessary», — said the Agency interlocutor.

According to the scientist, the question arises of what caused the increase in the level of ruthenium in the atmosphere.

«I don’t think that this «beacon», is unlikely, or he had to be identified in the concentrations of other radionuclides in pure it companies do not have», — said Yarmolenko, noting that to develop separately ruthenium-106 is a complicated procedure, it is a rather expensive material.

Funny storyexperts suggested that, since this radionuclide is used as a power source in space vehicles (fuel), the source of ruthenium-106 could be a fallen satellite. But the fall of such objects has not been fixed, and the source remains open, said the scientist.

So, doctor of chemical Sciences, academician Boris Myasoedov noted that if this «release» represented some kind of threat, were immediately taken: for example, restricting access to the street.

«Once the review was not followed, this indirectly means that no danger is not» — he said.

Commenting on the environmental situation in the Chelyabinsk region in General, the expert cited the example of the radiochemical plant in the town of Ozersk.

«There is processed is irradiated in nuclear power plants blocks. This, of course, released radioactive and volatile nuclides including ruthenium. But there are filters that ensure full absorption of these volatile substances,» he added.
