Abstract :
Abstract In this work the calculation of the concentration of Ra-226 (186 keV), Bi- 214 (609 keV), Cs-137 (662 keV),Ac-228 (969 keV) and K-40 (1460keV) in some samples of soil in Jisr Diyala / Baghdad have been done by gamma- ray spectroscopy NaI(TL) scintillation detector. The range of Ra226 activity was 0 Bq/kg for the sample (4), while the highest specific activity was (388.8) Bq/kg for sample (2), the mean with the total number of samples was (66.216) Bq/kg. The concentrations of radon gas in the air was determined. The doses resulting from the consumption of those were coming from the inhalation of radon gas were estimated using some of mathematical equations , it is found that the specific activity for all radionuclides are below the allowed value except in sample 2, this region was near the Iraqi Atomic Energy in Al-Twetha city.
