Sakellariou, A. Angelopoulos, L. Sakelliou, P. Sandilos, D. Sotiriou, Ch. Proukakis] The results of indoor external irradiation measurements in Greek dwellings are presented. The survey has been carried out in 33 municipalities and communities, in which about half of the total population of Greece resides. LiF thermoluminescence dosemeters (TLD-100), specifically calibrated in the low dose range, were used. The indoor absorbed dose rate in air due to external irradiation from terrestrial sources was found to be in the range of 9.1 to 151.9 nGy.h-1, with a mean value equal to 47.8 ± 22.1 nGy.h-1. The highest measured values are from Northern Greece (Macedonia and Thrace) in accordance with the corresponding outdoor data reported in the literature. The indoor to outdoor ratio for the terrestrial component was calculated and found to have a mean value equal to 0.99 ± 0.43. Based on these results, the total annual effective dose equivalent, from natural background radiation due to external irradiation, weighted over the Greek population, is estimated to be 550 ± 64 µSv.y-1, of which (78% can be attributed to indoor and (22% to outdoor irradiation, while (56% is due to terrestrial and (44% to extraterrestrial sources.
