Abstract: | In this work an identification of the ratio active nuclide in soil samples of Baghdad city with the measurement of there specific activity using Gamma-ray spectrometry is given. Twenty six samples of surface soil from Al-Kharch side and Four tenth samples from Al-Rusafa side are collected. Their positions are allocated using GPS system. A Gamma-ray spectrometry system type (DSA2000) is used in measurements with (HpGe) detector with 50% efficiency and 2.2 keV at the 1332 keV line emitted from (60Co) source. The results of specific activity averages of the radio active nuclide (208Tl or 228Ac) , (214Pb or 214Bi) , (40K) , (137Cs) in surface soil of Al-Kharch and Al-Rusafa sides are (47.199±2.047), (47.032±3.147), (819.901±11.134), (7.49±0.759) Bq/kg respectively for Al-Kharch soil and (51.703±2.229), (49.388±32.361), (852.715±1.798), (7.54±0.804) Bq/kg for Al-Rusafa soil, which are close, for example, to the uranium percentage as estimated by (UNCERR) which is (48.89) Bq/kg. It may be concluded that no indication of high level of specific activity is observed and results are within the ordinary levels. |
