Abstract
The gamma-ray transmission method has been used to study the soil-water properties in the laboratory as well as in the field. The present measurements were performed using gamma-ray spectroscopy system based on a 5 x 5 cm Nal (T 1) scintillation detector and combined sources ({sup 137} Cs and {sup 241} Am). The two sources are placed in a suitable lead collimator to obtain a pin beam of 1 mm diameter. Suitable samples of clay and sandy soils obtained from the local field were prepared to determine the water content and the soil bulk densities by the combined method for different moisture stages. From the results obtained, it is clear that the soil density at both stages (saturated and after drainage) remains the same. this is because the soil particles do not rearrange during the wetting and drying process. The full results will be presented in the text. Natural radioactivity of the investigated samples was also studied using gamma-ray spectrometer having HPGe detector. Qualitative and quantitative analysis of natural gamma radiations revealed the presence of {sup 40} K, {sup 214} Bi, {sup 208} TI and {sup 228} Ac in meaningful concentrations. 3 figs.
