Comparison of direct alpha and charcoal adsorption methods in field measurements of radon flux
AbstractA survey of radon fluxes originating from phospho-gypsum tailings ponds was carried out by two independent groups. One group utilized direct measurement of alpha activity using a scintillation counter. The other group used charcoal cannisters to accumulate radon and subsequently measured 214Bi gamma activity. In this report, we examine the agreement between values obtained by both methods at several locations. We find a high degree of correlation especially when one considers that the charcoal measurements were made over a period of about 24 hours, whereas the scintillator readings recorded the build up of radon in an inverted 20 litre container after only 1 hour.
