Effect of Geometrical Constraints on The Intensity of Multiple Scattered Gamma Photons in Soil Medium

Abstract

Transverse thickness as well as the distance between source (¹³⁷Cs) and detector was varied in soil medium keeping fixed longitudinal thickness to investigate the variation of intensity of multiple scattered gamma rays with geometrical changes. The obtained results are in good agreement with our previous findings in which source and detector were kept fixed and the dimensions of soil medium were varied. It is reported here that the intensity of multiple scatter photons depends on the thickness of the interacting medium between the source and detector not on the geometrical constraints.
