In this work, we have study the concentration of radon gas in seven cement samples from different regions in Iraq (Kofa, Sulaymaniya, Kubesa, Karbala, Al-Kaem, Basra, and Almas cement) by using alpha-emitters registrations that emitted from radon gas in CR-39 nuclear track detector. Sealed-cup technique that used in this study to determine the alpha emitters from radon gas. The results obtained shown that the highest average radon gas concentration in cement samples which was (55.16 Bq/m 3 ) for Almas samples, while the lowest average radon gas concentration in cement samples which was (24.13 Bq/m 3 ) for Karbala samples. The current results show that the radon gas concentration in all cement samples that studied is below the allowed limit from International Commission of Radiation Protection (ICRP) agency.
