Radon in indoor air originates from trace concentrations of radium in substrate soil and the walls, floor and ceilings which are constructed of building materials [1]. According to the assessments made by the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), radon in the natural environment constitutes about 50% of the human exposure to natural radiation or 1,2 mSv/year [3]. In this paper are given the results of the indoor radon concentration measurement of about 173 dwellings which involving 10 Albanian Regions performed by the Centre of Applied Nuclear Physics. For these measurements were used passive radon detector Radtrack, which provide the average values of indoor radon concentration for 90 days (3 months). Regional averages range from about 23 Bq m(-3) to about 278 Bq m(-3). However, the uncertainty of regional values can be relevant in case of small Regions, where a low number of small dwellings, although such uncertainties do not affect significantly national values. Based at the results of the measurements, the indoor radon concentrations in the majority of the dwellings were under reference levels (200-400 Bqm(-3)) [2].
