Abstract

This work studied about the angular and intensity distributions on multiple scattering gamma energy 662 keV, obtained from 137Cs source. The gamma photons are incident on aluminium scatterer of varying thickness is studied experimentally in both the forward and backward hemispheres. The observed spectra recorded by a properly shielded NaI(Tl) scintillation detector. To extract the contribution of multiply scattered photons having same energy as in the singly scattered distribution from the measured spectra, a singly scattered distribution is reconstructed analytically. We observed that the number of multiply scattered photons also increases and saturates at a particular value of the scaterrer thickness and determined at different scattering angles. ฉ (2014) Trans Tech Publications, Switzerland.
