Determination of radon gas concentrations in cement samples by using nuclear track detector (CR-39)

Abstract

In the present work, we have measured the radon gas concentration in nine cement samples available from the local markets, and from different countries like, (Iraq ,China , Egypt ,Lebanon, India ,Iran, AL-Saudia,Jordan and Turkyi) by using alpha-emitters registrations which are emitted from radon gas in (CR-39) nuclear track detector.The results obtained have shown that the highest average radon gas concentration in cement samples which was (199.99 Bq/m3) origin Iran, while the lowest average radon gas concentration in cement samples which was (79.99 Bq/m3) origin Iraq .The present results show that the radon gas concentration in all cements samples is below the allowed limit from (International Commission of Radiation Protection) (ICRP) agency.
