Study of indoor radon and radon in drinking water in Greece and Cyprus: Implications to exposure and dose

This paper reports passive and active radon concentrations in indoor air and drinking waters in Cyprus and Greece (Attica, Crete) together with exposure-dose estimations. Passive indoor radon concentrations in Cyprus ranged between (14 +/- 3) and (74 +/- 6) Bq m(-3) (arithmetic mean, A.M., 29.3 Bq m(-3)). Active indoor radon concentrations in Attica ranged between (5.6 +/- 1.8) and (161 +/- 12) Bq m-3 (A.M. 27.6 Bq m(-3)) and in Crete, between (1.7 +/- 0.4) and (141 +/- 12) Bq m(-3) (A.M. 23.4 Bq m(-3)), The radon concentrations in drinking waters in Cyprus ranged between (0.3 +/- 0.3) and (20 +/- 2) Bq L-1 (A.M. 5.9 Bq L-1) and in Greece between (0.8 +/- 0.2) and (24 +/- 6) Bq L-1 (A.M. 5.4 Bq L-1). Radon is the main source of exposure and dose in both Greek and Cypriot population. (C) 2008 Elsevier Ltd. All rights reserved.
