Using the gamma spectrometry method to determine the concentration of radon in samples of mineral radon water

The results of a study on the choice optimal measurement geometry, measuring capacity and method sealing for determining concentration radon-222 in samples mineral radon water are presented. Studies were carried out laboratory conditions stationary gamma spectrometer based semiconductor Ge(Li) detector. measurements accordance with MVI. MN 3421-2010 “Methodology volumetric gamma-emitting radionuclides spectrometers detectors” standard plastic vessels “Denta, 0.1 l” “Marinelli, 1 l”, glass containers volume 0.5 l lids twisting seaming. research showed that leakage from container metal lid is minimal. This sampling vessel makes it possible to increase accuracy presented by reducing corrections sample preparation when calculating expanded uncertainty. A cap seaming was used measure taken wells drinking fountain Radon sanatorium Belagrozdravnitsa JSC (Dyatlovo District, Grodno Region). range 760–2100 Bq/kg. selected container, its geometry can be future sanatoriums Republic Belarus.
