<br/><br/> The aim of this work is to study the natural radioactive properties in Tushka area and elemental and isotopic analysis of some environmental samples (soil and rocks) in Tushka areaAlso , to detect its components of some selected heavy metals or toxic elements which may be dangerous to humans as well as living organisms during its transport through the food chainFurther more , the study of the concentration of Uranium - 238 , Thorium - 232 , and Potassium - 40 in these soils will be carried outThe study concerned with calculation of the absorbed dose rates and annual effective dose of the studied area
