AbstractFirst part to determination concentrations of Rn-222 in surface samples of soil, the highest average concentration of Rn-222 was found in AL-Refai region was equal to (127.500±2 Bq/m3), while lowest the average was found in AL-Aekeckh region which was equal to (33.750±2.2 Bq/m3), with an average value of (75.875±21.8 Bq/m3) ,while the (RER) was found to be ranged from (36.821 mBq/m2h) (T19 region) to (139.103 mBq/m2h) (T1 region), with average value (82.780±18.6 mBq/m2h), second part to determine of concentration of Rn-222 in samples of soil from depth 10 cm , the highest average concentration of radon in AL-Refai region which was equal to (109.500±7.7 Bq/m3), while the lowest average concentration of Rn-222 gas was found in AL-Aekeckh region equal to (30.250±2.9 Bq/m3), with an average value (66.703±14.8 Bq/m3), while (RER) was found to be ranged from (33.003 mBq/m2h) (T19 region) to (119.465 mBq/m2h) (T1 region) ,with value of average (72.784±16.2 mBq/m2h).The concentration of Rn-222 in surface soil and at depth (10 cm) were less than the recommended value given (ICRP, 1993).
