In this work, radon concentrations were measured in dwellings Kufa Technical institute, Iraq between November 2014 to February 2015 using time integrated passive radon dosimeters containing LR-115 Type II plastic track detectors. Also, we calculated the concentration of short-lived radon daughters, potential alpha energy, working level month, the annual effective dose rate, the annual equivalent dose rate and the excess lifetime cancer risk in all dwellings under study. The radon concentration in these dwelling ranges from (15.211 ± 2.745 to 32.445 ± 09.200) Bq/m3 with an average of (21.567 Bq/m3), which within the acceptable radon levels (50-150) Bq/m3 recommended by the International Commission on Radiological Protection (ICRP). The mean the excess lifetime cancer risk were found to be ranges from 35.458 to 75.633 with an average value of 50.297 per 106 persons. These values are within in the safe limits recommended by the international organizations.
