Fast determination of indoor radon ((222)Rn) concentration using liquid scintillation counting
The indoor (222)Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing −3 dm(3) 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: (218)Po and (21...

| Sumario: | The indoor (222)Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing −3 dm(3) 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: (218)Po and (214)Po, was determined with the BetaScout low-background liquid scintillation counter. The limit of (222)Rn detection is 9 Bq/m(3), and the quantification limit with 20% relative accuracy is 28 Bq/m(3). The results of the indoor Rn measurement in different houses showed good consistency with results obtained from a Sarad EQF 3220 device. |
