Investigations of energy dependence of saturation thickness of multiply backscattered gamma photons in elements and alloys - an inverse matrix approach

Abstract: Abstract. In Compton scattering experiments employing thick targets one observes that the numbers of multiply backscattered photons increases with increase in target thickness and then saturate at a particular target thickness called the saturation thickness. The energy of each of gamma ray photons continues to decrease as the number of scatterings, the photon undergoes, increases in the sample having finite dimensions. The present experiment is an independent study of energy and intensity distributions of 279… Show more

“…On the other hand, number of multiply scattered events decreases with increasing energy of incident photons because the penetration of gamma ray photons increases with increase in incident energy. This behaviour is in agreement with experimental results obtained from the works of Sabharwal et al [1,3,6,14]. The values of the saturation thicknesses, being compared with experiment and MCNP [2], are presented in Table I.…”

“…The backscattering of gamma rays from the surface of a material is of fundamental importance in radiation shielding, radiation absorption and non-destructive testing of finite samples of industrial, medical and agricultural interest [1]. When gamma rays are allowed to interact with thick targets, they undergo multiple scattering incidents within the dimensions of the target before they escape from it [2].…”

“…The BSF of a phantom for a dosimeter is an important parameter for accurate dose estimation in terms of operational quantity, Hp(10). Since the number of multiple backscattered events increases with decrease in photon energy and is saturated with an increase in target thickness (Sabharwal et al, 2009a(Sabharwal et al, , 2009bAkar et al, 2012), backscattered photons from a phantom are expected to be optimum at 662 keV calibration photon energy.…”
