Study The Radiatory Pollution in Selected Soils of Kirkuk Governorate

Abstract

18 samples of soil were collected from selected places in Al¬-Tamim governorate and these samples were measured by using Gamma ray spectrum system represented by Germanium high purity (HPGe) with energy resolution 2.2 KeV at the energy 1332 KeV of Co60. The system was attached to the computer where the spectrum was collected and analyzed by the PCA program which is a comprehensive program for spectral and quantity analysis of Gamma ray. The radiatary activity of radiating nuclides resulting from the chain of U238,U235, K40 and Cs137 were calculated . The ratios Th234 /Ra226, was found (0.828 – 0.969), Th234 /Pa234m, was found to be (0.805 – 0.954).The value of R which represents U235/ U238 was counted and it ranged between (0.00562-0.00602) for the samples of polluted soils and (0.0064-0.0071) for
