The current research aims to measure radon gas concentrations in different types of tobacco. 20 types of cigarettes tobacco and two types of molasses were collected for eight different companies the most prevalent in smoking which are found in local markets using the techniques of solid state nuclear track detector CR-39 and electronic radon detector RAD7. The results showed that the radon gas concentration ranged between (44.54-100.22) Bq m-³ in cigarette samples and its concentration in molasses samples ranged between (40.02-134.98) Bq m-³ CR-39 detector. The results showed that radon gas concentration ranged between (41.9-84.1) Bq m-³ in cigarette samples (BD-BP). The ranged between (40.4-82.1) Bq m-³ in molasses samples (Gr2-Gk2) using the RAD7 reagent technique. The results of the study shows that the radon concentrations in tobacco samples are less than the internationally allowed limit (200-300 Bq m-3).

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/m
3
) ,while the lowest one was found in
(Saudi) sample, and found to be (2.486Bq/m
3
). The present results show that the radon gas
concentration in all cement samples is not below the allowed limit from (ICRP) agency.
