Simulated and experimental calculation of backscattering area with different scatterers

In the past decade, there has been an extensive experimental investigation on gamma backscattering technique, however systematic investigation for wide range of metals is yet to be conclusively explored. The experimental measurement of the Albedo Factor is also limited to a few elements and is yet to investigate significant range of metals. The area under the backscattering peak is a factor of the scattering materials and their thickness. The simulation and the experiment use ¹³⁷Cs as a gamma source. The simulation used various precious and non-precious metals as the scatterers to find the area under the peak, however, due to procurement limitations associated with precious metals, the experimental setup used materials with similar Z as the precious metals. The simulation was done using GEANT4 software, while the experimental analysis was done using CANDLE software
