The indoor Rn radionuclide was directly absorbed in typical 20 ml glass scintillation vials by passing -3 dm 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 -emitting daughters: Po and Po, was determined with the BetaScout low-background liquid scintillation counter. The limit of Rn detection is 9 Bq/m, and the quantification limit with 20% relative accuracy is 28 Bq/m. The results of the indoor Rn measurement in different houses showed good consistency with results obtained from a Sarad EQF 3220 device.
通过使3立方分米的环境空气通过16毫升水不混溶的非挥发性闪烁鸡尾酒Ultima-Gold F 10分钟，将室内氡放射性核素直接吸收到典型的20毫升玻璃闪烁瓶中。用BetaScout低本底液体闪烁计数器测定氡及其两个发射β粒子的子体：钋-218和钋-214的活度。氡的检测限为9贝克勒尔/立方米，相对准确度为20%时的定量限为28贝克勒尔/立方米。不同房屋室内氡测量结果与Sarad EQF 3220设备获得的结果具有良好的一致性。
