This paper presents an evaluation radiation pollution of groundwater and the radioactive contamination from natural radiation sources using sodium iodide detector by measuring gamma lines emitted from radioisotopes. The radioactivity of the radioisotopes radium (Ra226), Actinium (Ac228) and potassium (K40) were identified in the studied samples, which included 52 different groundwater samples in the city of Al-Tuz, Salah Al-Din Governorate, Iraq. The results show that the concentration of Ra226 was between the range (w22 (3.712)-w45 (191.551)) BqL-1, where some of samples radioactivity was higher than the allowed limit (35BqL-1), but the concentration of Ac228 was between (w25 (1.609)- w29 (42.4) BqL-1) and the concentration of K40 was between (w1 (1.092) - w18 (123.164)) Bq L-1 where all the results were below the allowed limit of (400BqL-1), and the radium equivalent was between (w22 (20.613434) -W45 (212.02739))BqL-1, where all the results were below the global limit (370) BqL-1. The rate of absorbed dose AD was between (9.7047138-97.434442) nGyh-1 that 20 samples appeared above the allowed limit and the rest of the samples was less than the allowed limit (84Bq L-1). The annual effective dose of Ra226 concentration was between (0.065097- 0.001261) mSv/year showed that all the results were less than the global limit of (0.1 mSv / year).
