This research paper desired to illustrate the presence of naturally occurring radioactive minerals concentration and the way how naturally occurring radioactive minerals were identified in Wag-himra iron ore deposit soil site. The deposit area covers five Kebelles of the border of Sekota, Ziquale and Abergelle districts. We were used high pure germanium detector to identify the presence of natural occurring radioactivity concentration in iron ore/alloy deposit soil, and applied appropriate research methodology particularly experimental design were more preferable. The researcher was collected samples from ten places across iron ore deposit area by using judgmental sampling techniques and prepared as a desirable manner. The chosen sample was sealed for four weeks in order to obtain secular equilibrium, wherein the rate of decay of the daughter's equivalent that of the parent. Radium equivalent activity, external hazard index and representative gamma index of the sample were 56.19, 0.1515, 0.804, 0.408, 0.00011 (Bq/kg) respectively. However, internal hazard index was slightly approaching to recommended value and it may cause the significant radiation hazard through long dwelling to the area. This study NORM was analysis from sample of soil from at mineral/iron ore deposit area. The natural occurrence of radioactive materials identified in the samples were 238 U, 232 Th and 40 K. The radiation hazardous were external and internal index.

The current study looked at the concentration of naturally occurring radioactivity and radiation hazards in iron ore deposited in soil. The aim of this study was to identify the dose of radiation which is emitted from rocks, soil and some building materials, the radiation dose and the effect in the area. In this work, analyses of the sample soils were performed with a computer-based gamma-spectrometry system with software of G-2000 for qualitative and quantitative determination of gamma-emitting radionuclide of natural occurrence of radioactive materials. The quantitative investigation of natural radioactive materials of 238 U, 232 Th and 40 K were 11.688±0.42Bq/kg, 23.505±0.925Bq/kg and 141.48±4.403Bq/kg respectively. In addition to this, the results of absorbed dose rate, annual effective dose equivalent, radium equivalent activity and representative gamma index of the sample were much less as compared to recommended international values by UNSCEAR-2000. At low activity concentrations of the radionuclides produce low background radiation to the environment. The value obtained from the experiment reveals that the radiation hazards emitted by natural radionuclides in the soil cause insignificant harm to the public from the Wag-himra iron ore deposit soil. The concentration of natural radioactive elements in this area's soil could be used for construction purposes without causing any significant radiological hazards to humans for the time being.
