Indoor Radon Concentrations Measurements for Selected Dwellings in Some Baghdad Districts – Iraq

In this work, measurements of indoor radon concentrations were completed for selected dwellings in Baghdad governorate using DURRIDGE RAD7 detector. The spectra measured by this detector demonstrated that, the radon concentrations were changed from 89 Bq/m 3 (Hay Ur district) to 191 Bq/m 3 (Al-Mansour district) with an average value of 123.3±24.3 Bq/m 3 which is below the recommended range (200-300 Bq/m 3 ) given by (ICRP, 2009). All other studied parameters such as EP, PAEC, AED and CPPP their values were less than or corresponding to the allowed worldwide average values.
