Natural radioactivity measurements in soil and phosphate samples from El-Sabaea, Aswan, Egypt

The knowledge on radioactivity content of the various radionuclides in the soil and rocks play an important role in health physics. The main aim of this work is to estimate the concentrations of natural radionuclides {sup 226}Ra, {sup 228}Ra, {sup 228}Th, {sup 232}Th and {sup 40}k in soil and phosphate samples and, impact of the El-Sabaea phosphate factory on the human health. This can be investigated via gamma-ray spectroscopy by 2 x 2 inch NaI(Tl) scintillation detector. The range of {sup 226}Ra, {sup 232}Th and 40k were from 59.7{+-}6.7 to 638.3{+-}31.0, from 9.4{+-}1.4 to 40.6{+-}6.3, from 213.1{+-}9.5 to 798.9{+-}30.6 in Bq/kg respectively.
