Mapping of Radioactivity in Soil of University of Kerbala Iraq

Soil is one of the most natural sources of ionizing radionuclides such as Uranium-238 (238U) series Thorium-232 232Th series and Potassium-40 (40k) as single series that may affect human health.100 soil samples were collected from different locations of University of Karbala that consists of many colleges distributed in three sites such as Freiha site Al-Husseineya site and Al-Mothafeen site.Gamma-ray emitters (238U 232Th and 40k) and alpha emitters (222Rn 226Ra and 238U) were measured by gamma-ray spectroscopy (NaI(Tl) with 3×3 dimension) and solid state nuclear track detector (CN-85 detector) respectively. As well as radiological hazard index due to gamma and alpha emitters of samples were determined.
