Optimization of AlphaGuard AquaKIT set-up for analysis of radon in water using stainless-steel bottles and its validation through IAEA standard samples

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-ste...

Sumario: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.
