Abstract
Analyzed the problem of radon safety in residential areas with gas stoves of various companies. Volumetric radon concentrations were obtained and annual dose rates were calculated. Measurements were carried out with two instruments: on the radon gauge Alpha Guard and on the PPA-01M-03 manufactured by NTM - Protection. Samples of networked natural gas for measurement were taken using an air sampler [1], [2]. A device and methods for sampling methane from domestic gas cookers in the conditions of the city of Yakutsk have been developed. The sampler consists of a silicone hose with a tubular tip with a solid cap. Silicone hose attached to the standard air sampler with two fittings of the company NTM Protection. The divider and the burner are removed from the tile; the tube with the cap is pressed tightly against the iron gas-conducting pipe. The methane launch valve opens to the stove. A flexible tube is put on the loose fitting and lowered into a bowl of water to control the gas outlet. Experimentally chosen time to achieve the maximum volumetric concentration of radon in the sampler for air. The obtained value of radon volumetric activity is: 116 ± 27 Bq/m3
