Abstract
In the present work, have measured the radon gas concentration in ten cement samples from different countries like, (Iraq,Egypt,Iran,Lebanon,Turkyi and Jordan) by using alpha-emitters registrations which are emitted from radon gas in (CR-39) nuclear track detector.
The obtained results have shown that the Maximum average value of radon gas concentration in cement samples which was (37.68 Bq/m3) origin of Turkish, while the lowest average of radon gas concentration in cement samples Delete which was (17.87 Bq/m3) origin of Iraq (Najif).The present results Show the radon gas concentration in all cements samples was below the allowed limit from (International Commission of Radiation Protection) (ICRP) agency.
