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

Abstract

In the present work, we have measured the radon gas concentration in ten cement samples from different countries ,they are , (Iraq, Egypt ,Iran, Lebanon ,Turkyi and Jordan) by using alpha-emitters registrations which are emitted form radon gas in (CR-39) nuclear trackdetector. The results obtained have shown that the highest average radon gas concentration in cement samples which was (200 Bq/m3) origin Iran, while the lowest average radon gas concentration in cement samples which was (84.4 Bq/m3) origin Iraq (Najif).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.
