| This study was intended to analyze and evaluate the radioactivity level of radioactive nuclides, 26Ra, 232Th, and 40k of different kinds of Natural waters for various regions of the Nineveh Province in Iraq. To achieve the objective of the study, 30-samples of Natural wa±ter were taken from various sources. The water samples were distributed in three types: 8 samples of surface raw water, 13 samples of tap water, 5 samples of cold well (underground) water, 3 samples of mineral spring water, and one rainwater sample. Gamma-ray spectroscopy using a NaI (TI) scintillation detector attached to a software multi-channel analysis tool was used to determine the radioactivity concentration in the samples. In the investigated samples of Natural water, the radioactivity concentrations of 226Ra, 232Th, and 40k ranged between (4.67± 0.26 - 22.95 ± 0.58) Bq/l for 226Ra, and between (4.44±0.38– 1.85 ±0.07) Bq/l for 232Th, while 40k ranged between (7.24±0.52 -38.49±1.20)Bq/l, respectively. The results obtained from the samples of water were below the safe and standard limits established by UNSCEAR, with the exception of one site due to their geological nature. Radium activity equivalents (Raeq), Absorbed dose rate in the air (Dγ), effective dose rate per year, and the gamma radiation level index (Iγ) were calculated to investigate their harmful character. Radiological hazard indicators appeared to be below the international permissible rate. The current study's findings can be used to provide essential basic data for future epidemiological investigations and surveillance programs in the study area. | ||||
