Calculations of the transmitted gamma photons through infinite slabs
The intensity and number of transmitted multiple scattered photons are calculated for 0.123, 0.320, 0.511, 0.662, and 1.115 MeV gamma photons normally incident on slabs of carbon, aluminum, iron, copper, water, muscle, bone, and concrete with thicknesses varying from 1 to 10 mean free paths. The dependence of the transmission probability and energy distribution on the incident energy and material are examined. In general, the obtained results show good agreement with the other values calculated by the Monte Carlo method.
