Uranium Concentration Measurements in Al- Dura Soil of Baghdad Governorate using pm - 355 Detector

Abstract

The nuclear track registration technique with pm-355detector used to determine the uranium concentrations for twenty-eight samples of soil distributed in seven districts for Al-Durra city in Baghdad governorate with depth (5) cm .The uranium concentration in soil samples measured by bombardment uranium with thermal neutron from (241Am-Be) source that has flux of (5x103n.cm-1). The concentration values were calculated and comprised with standard samples .the results showed that the maximum value of uranium was (1.478ppm) in Al-Gameaea district and the minimum value was (0.676ppm) in Al-Maelemeen district.
