Distortion of radiation background in urban environment due to aggressive influence of technosphere. stage 1: radon and alpha-background

The work is devoted to testing the possibility of replacing industrially produced radon radiometers with more economical detectors of alpha and/or beta-radiation for conducting year-round and periodic monitoring of radon in the urban atmosphere. A significant correlation was revealed between the integral (monthly average) values of the EEC of radon and the flux density of alpha radiation. This confirms that the monitoring of the alpha background in the urban environment can reliably replace the monitoring of the EEC of radon, which is normalized and characterizes the internal exposure of the population to alpha radiation. It was found that with a known seasonal pattern in the dynamics of the coefficient of radioactive equilibrium between radon and its daughter decay products, it will also be possible to replace monitoring of radon in the urban atmosphere by monitoring the flux density of alpha radiation.
