The paper presents and discusses radon activity concentrations in Cypriot groundwater systems as a function of the background lithology and seasonal/meteorological conditions using an airborne radon monitoring system (ARM) after separation of radon by out-gassing. Radiometric analysis of groundwater samples obtained from non-contaminated systems showed that radon concentration in groundwaters varies strongly (0.1-10 Bq L-1) depending mainly on the hosting geological matrix but also to lesser degree on atmospheric/meteorological conditions. The associated excess annual dose has been estimated to range between 10(-6) and 10(-4) mSv y(-1), which is an insignificant contribution to the radiation exposure of the Cypriot population caused by airborne radon (0.5 +/- A 0.4 mSv y(-1)).
