How to Collect a Radon in Water Sample
Radon in water poses both an inhalation risk and an ingestion risk. Research has shown that your lung cancer risk from breathing radon in air is much larger than your risk of stomach cancer from swallowing radon in water.
Most of your risk from radon in water comes from radon released into the air when water is used for showering and other household purposes. Radon in water is not usually a problem when your home's source is surface water.
A radon in water problem is more likely when its source is ground water, e.g. a private well or a public water supply system that uses ground water. You should use our WT-100 radon water kit if your water comes from a well.
Collecting a Radon in Water Sample
One method of collecting a radon water sample is to slowly fill a bowl or deep pan. Submerge the radon water collection vial and cap open side up until they fill. While the radon water sample vial is still submerged, screw the cap of the vial back on. The radon water sample should not contain any air bubbles or have any headspace. The radon water sample collection vial does not contain a preservative. If there are any air bubbles in the radon water sample, collect the sample again. Return the radon water sample to be received by the laboratory within four days.
