ABSTRACT

The comparative measurements of radon Rn-222 concentration in indoor air of some buildings and in radon labour chamber have been conducted using two different diffusions methods. The results of parallel measurements using radon charcoal detectors and gamma-rays spectrometry with liquid alpha scintillation counting (Pico-Rad) have been presented. It was concluded that both methods offer the similar measurements possibilities of radon concentrations in the air from about 30 Bq/m3 to about 600 Bq/m3 with the real average divergence between both metods of about ±11%.
