摘要：
The current study aims to estimate the radiological hazard of the investigated granitic rocks by radioactive methods for the geo-chemical analyses, practically the activity levels and distribution of natural terrestrial radionuclides of Ra-226, Th-232 and K-40 were measured by ICP and XRF for samples of the investigated granitic rocks collected from Urn Taghir area. The purpose of the study was to determine the radiological hazards of investigated granites to use in the field of construction and adornment or not and the extent of their impact on those who use them in their homes or for other purposes. We concluded that the average value of Ra-eq, was found to be 88.78 Bq kg(-1) as well as the estimated highest value of 141.38 Bq kg(-1) of Ra-eq, in the present work was lower than that of the recommended maximum value of 370 Bq kg(-1). The range of measured activities differed widely as their presence in rocks samples depends on their physical, chemical and geo-chemical properties and the pertinent environment.
