Abstract:
Transmitted photon spectra (pulse-height distribution) of (137)Cs gamma rays are measured through longitudinal and transverse dimensions of the soil medium. The intensity (photon fluence rate) of the multiple-scattered peak, appearing in the lower energy part of the spectrum, has been studied as a function of longitudinal as well as transverse thickness of the soil medium. The intensity of multiple-scatter peak decreases exponentially with the increase in longitudinal thickness of the soil medium, whereas a reverse trend of multiple-scatter peak intensity with transverse thickness occurs as the longitudinal dimension increases. The soil medium as a whole takes part in multiple scattering affecting the intensities of transmitted photons.
