2001, Planetary and Space ScienceCitation Excerpt :A Monte Carlo code was developed to follow the scattering and absorption histories of a large number of photons (emitted by a point source) in a semi-infinite bulk material of uniform bulk density. The code was first used to study the backscatter of 241Am photons for the original MUPUS densitometer design concept (Ball et al., 1996) and has since been improved and extended to allow simulation of the attenuation concept. The code does not model the detector response but can provide the basic properties (position, direction and energy) of photons passing through one or more ‘virtual detectors’ at or above the material's surface.
