In this study, a system composed of an ionization chamber AlphaGUARD (PQ 2000), an AquaKIT set and an AlphaPUMP was calibrated to measure ²²²Rn in water. First, the system was checked for leakages using a NIST traceable ²²⁶Ra source. Then, we tested polyethylene terephthalate (PET) and stainless-steel bottles for sample storage estimating radon loss over time. Results showed that stainless-steel was a better suitable material for sample storage. Additionally, system setup was further validated by measuring IAEA reference materials issued within the framework of several interlaboratory intercomparisons. Finally, the procedure was applied to bottled mineral and tap waters collected in Sevilla (Spain) including annual effective dose for ingestion for adults children, and infants.

在这项研究中，对由电离室AlphaGUARD（PQ 2000），AquaKIT套件和AlphaPUMP组成的系统进行了校准，以测量水中的²²² Rn。首先，使用NIST可追踪的²²⁶ Ra源检查系统是否泄漏。然后，我们测试了聚对苯二甲酸乙二醇酯（PET）和不锈钢瓶的样品存储量，以估计随时间的ra损失。结果表明，不锈钢是更适合样品存储的材料。此外，通过测量在若干实验室间比对框架内发布的国际原子能机构参考材料，进一步验证了系统设置。最后，该程序应用于在塞维利亚（西班牙）收集的瓶装矿泉水和自来水，包括成年儿童和婴儿的年度有效摄入剂量。
