Natural Radioactivity in Underground Waters in Tallafar Distract in Iraq

Abstract

The purpose of the present study is to measure the level of the natural radioactivity of (underground waters samples) in Tallafar district center, from the Alayadiyah side, and from the Al-Adaya village, determination of specific activities of (228Ac,226Ra,214Pb, 137Cs, 40K), (0.40716), (0. 2321), (0. 281), (0.76751), (4.9806) Bq/L respectively using gamma ray spectroscopy technique with NaI(Tl) scintillation detector in 15 samples, also evaluation of radiological hazard indices(radium equivalent Reaq, absorbed dose rate(Dγ), annual effective dose (AEDE indoor), AEDE(outdoor), hazard induces (Hex and Hin) and gamma index (Iγ)). The results showed that the average value of the specific activity are agreement with IAEA publications.
