After closing the bottle airtight, the container was attached to RAD7 in a shut loophole. Radon was aerated from the water example making use of a constructed in pump for 5 min as well as moved via a desiccator column to the detector where 222Rn activity concentration was derived from counting the 218Po. The radon activity concentration at the time of the evaluation was considered as the mean worth offered by the instrument. The initial one uses an ionization chamber (AlphaGuard, Saphymo Gmbh) as well as the other one a semiconductor (RAD7, Durridge Company Inc.) counting system. For the AlphaGuard sample preparation, an aliquot of water was carefully moved from the original sampling container by a 100 mL syringe into a gas-tight glass degassing vessel.
