Abstract: In this work, radon concentration for the seasons 2017-2018 was measured in various buildings of Tikrit University by using the technique of calculating the track of alpha particles emitted from the dissolution of radon on the solid state nuclear track detector (SSNTDs) type CR-39. The results of the first season samples collected in October 2017 showed that the concentration of Rn222 is from the lowest value of PHs3 (36.35 18.04 Bq / m3) to the highest value of B3-1 (270.50 32.86 Bq / m3) The average concentration is (147.18 45.56 Bq / m3). The results for the second season of January 2018 were the lowest for P3 (71.57 14.40 Bq / m3) and the highest value of B2-1 (278.95 19.20 Bq / m3) while the The averageis (150.41 52.20Bq / m3) All These radon concentrations are within the recommended natural concentrations of the International Atomic Energy Agency (IAEA) [ICRP, 1993] Annual effective dose values, lung cancer risk per 1 million LCR, and alpha energy concentrations were calculated, the results were lower than those recommended by the International Atomic Energy Agency [ICRP, 1993] and the Scientific Committee on the Track of Radiation of the United Nations [UNSCEAR.1993].
