“…The exposition of the open vial without bubbling can only be applied to high soil gas radon concentrations [ 13 , 14 ] or with a special counter construction with very low background for α –particle detection [ 18 , 19 ]. An alternative method, which depends on 10–20 l of air passing through 20 ml of scintillation solvent held at −78 °C in a bath of dry ice and acetone, gave satisfactory radon activities captured in scintillation vials, but its applications for routine large scale screening purposes are limited [ 16 , 17 ].…”

The indoor 222Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing −3 dm3 of ambient air through 16 ml of water-immiscible non-volataile scintillation cocktail Ultima-Gold F for 10 min. The activity of radon and its two α-emitting daughters: 218Po and 214Po, was determined with the BetaScout low-background liquid scintillation counter. The limit of 222Rn detection is 9 Bq/m3, and the quantification limit with 20% relative accuracy is 28 Bq/m3. The results of the indoor Rn measurement in different houses showed good consistency with results obtained from a Sarad EQF 3220 device.
