Abstract  
 
     In this work, we have measured the concentration of radon gas in eight cement samples from different origins by using long-term measurement of radon decay products with solid state track detectors which alpha particles that emitted from radon gas was detected using (LR115II) nuclear track detector.       The obtained results show that, the highest average radon gas concentration in cement samples was found in Iraq cement (Samawa) sample, which  was (10.625  Bq/m3)  ,while the lowest one  was found in (Saudi) sample, and  found to be (2.486Bq/m3). The present results show that the radon gas concentration in all cement samples is not below the allowed limit from   (ICRP) agency.
