Application of PENELOPE Code for Photon Transport Investigations in Lead and Aluminum Slabs
Photon transport studies in lead and aluminum slabs for photon energies of 60Co (1332keV, 1173keV),137Cs(661keV) and 241Am(59keV) were investigated using the PENELOPE code. Monte Carlo simulated results obtained are average results of transmitted, backscattered and absorbed photons in lead slab, aluminum slab and air (medium for comparison). A simulation period of five minutes reveals the dependence on photon's initial energy, slab thickness, angle of emergence, and scattering cross sections. Simulated polar exit angles of transmitted photons have show an average between zero and 20 degrees. Angles of backscattered photons are also within the range of 90 and 180 degrees, which are as expected by theory. Angle of exit of transmitted photons is between 0 and 90 degrees, also as expected, with a high peak between zero and one degrees. Thus, the Monte Carlo simulation is in conformity with theory which suggests that most experimental measurements involving photon transport can be handled by Monte Carlo techniques through the PENELOPE code.
