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).

This study aimed to estimate the level of leptin hormone and some biochemical variables in patients with lung cancer. Twenty five patients with lung cancer and 24 healthy control were enrolled in this study. The results showed a significant decrease in the level of leptin in patients with lung cancer compared to healthy control. In group of patients with lung cancer who had BMI ( 20 – 23 kg/m2 ), ( 24–26 kg/m2 ), ( more than 30 kg/m2 ) the levels of leptin were (1.42 ± 0.54), (4.35 ± 2.19), (8.75 ± 1.2) ng/ml respectively, comparing with the healthy control (4.89 ± 1.29), (6.85 ± 1.49), (9.85 ± 2.62) ng/ml respectively. The results also showed that there was a significant increase in activity of ALT in patients group (30.8 ± 16.4) U/L compared to healthy control (22.8 ± 6.55), while there was no statistically significant differences in the activity of AST in patients group (25.4 ± 8.9) U/L compared to healthy control (27 ± 9.2). There were no statistically significant correlation between leptin level with ALT ( r = -0.104 ) and AST ( r = 0.092 ). AST ( r = 0.092).
