The one of these geothermal areas is BayIndIr-Dereköy/Ergenli located in Küçük Menderes Graben. In this study, indoor radon concentrations were determined in some places (spas and some dwellings) located on BayIndIr-Dereköy/Ergenli. Measurements were realized using LR-115 type 2 solid state nuclear track detectors in the course of 10 months. The indoor radon concentrations were found between 39.3 and 235.4 Bq m -3 for spas, 39.3 and 405 Bq m -3 for houses. Indoor radon concentrations were compared with reference levels determined by international agencies. Radon concentrations in this area were quite low than reference levels revised by international health agencies. © 2013 Akadémiai Kiadó, Budapest, Hungary.en10.1007/s10967-013-2726-1info:eu-repo/semantics/closedAccessAnnual effective doseBayIndIrGeothermal areaIndoor radonArticle2991343349Q2
