The Radioactivity Environmental Monitoring Group (REM Group) of the European Commission's Joint Research Center, due to institutional scientific support, began to search radioactive radon gas in the interior of European homes in 2005, so that through the database the highly risk areas could be mentioned. Although this work has already been done to indoors radon concentrations in Greece, it should be repeated in time. In the present study, radon concentration in residential buildings is examined in the east (lowland area) of the prefecture of Chania. This study describes extensively, through a bibliographic overview, the phenomenon of radioactive gas "radon", which is a natural source of radiation that man receives in high percentage. Particularly, are presented radon natural sources, methods of air release and diffusion, measurement techniques, exposure hazards, removal procedures, methods for mitigation and prevention of buildings interior, as well as the applicable regulations in Greece and abroad, and measurement results from several cities in Greece. The geological and geomorphological characteristics of the west mountainous investigated area are also described. Radon concentration measurements were performed using passive Solid State Nuclear Track Detectors (CR-39). The grant of the detectors and their processing was done by the Environmental Radiation Control Department of the Hellenic Atomic Energy Commission. The results of indoor radon concentration measurements for the selected areas are presented in detail. Radon concentrations results are used to estimate the risk in these buildings by calculating active radiation dose (Eeff). Searching the parameters contributing to measured radon levels and active doses, data leads to the final conclusions.
