Measurement of dissolved radon in water over different seasons from a typical home in Maryland

Dissolved radon in water can contribute to the airborne radon in a residence. It was of interest to study whether there was nay seasonal variation of dissolved radon in water samples collected form a typical single family home using the well as a main source of water supply. Samples of tap water of known volume were collected in sample bottles and each sample was placed in a radon leaktight container in which an electret ion chamber radon monitor (E-PERMR) was present. The sample was spilled into the container, and the concentration of radon released into the container was measured using an E-PERM over a one-day period. A set of four such samples were analyzed every two weeks. Results included in this paper indicated that there was no significant change over different seasons and typically varied between 700 to 900 pCi/L for this particular well
