Recent high beta radioactive air pollution in nizhny novgorod and kirov
The Upper Volga UGMS at the end of January reported that the background value of the total beta activity in aerosol samples from Nizhny Novgorod and Kirov was exceeded by an order of magnitude.
What caused this? Leakage of radioactive materials from any industries?
Not. ')
It is just that during the winter period the burning of organic fuel by boilers increases, there is an additional influx of radionuclides of natural origin (radium-226and thorium-232) into the urban atmosphere.
Indeed, sometimes you want the cities of Russia to be heated not by burning fossil organic matter in boiler houses, but by powerful nuclear power plants located far beyond the city limits. Perhaps it would have been safer.
