摘要：

Gamma-ray transmission methods have been used accurately for the study of the properties of a porous medium such as soil. In this study, different soil parameters are determined by using gamma-ray transmission method. To this end, the soil samples were collected from various regions of Turkey and a NaI (T1) detector measured the attenuation of strongly collimated monoenergetic gamma beam through soil samples. The mass attenuation coefficients of dry soil samples were calculated from the transmission measurements for different photon energies. Furthermore, the soil samples were irrigated by adding known quantities of water and the soil-water properties were examined. The local water saturation and porosity were estimated from the transmission measurements for each soil sample. (C) 2002 Elsevier Science Ltd. All rights reserved.
