Radon levels in atmospheric and aquatic systems in Cyprus have recently been measured using the radon monitor Alpha Guard. Indoor and outdoor radon levels were obtained in situ, whereas analysis of radon concentrations in water was performed using tap and ground water samples collected from several areas of the island. The average value for outdoor and indoor radon concentration is 11±10 and 7±6 Bq m-3, respectively, and for tap and ground water 0.4 Bq l-1 and 1.4 Bq l-1, respectively. From these data the annual dose equivalent of airborne radon to the Cypriot population is about 0.19 mSv y-1, which is quite low compared to the total dose equivalent of natural and man-made ionising radiation in Cyprus. Radon levels in aquatic systems are relatively low due to an exhaustive utilisation of ground water resources and also to the increased input of desalinated sea water in the water distribution network and eventually into the ground water reservoirs. © 2003 Elsevier Science Ltd.
