Abstract:

The dimensions of many encapsulated gamma ray sources used in experiments are not small compared with the mean-free-path-length of the radiation within them. For this reason, the emitted radiation will not be at the source energies only, but will be distributed in a continuous spectrum. Furthermore, if the source is cylindrical, the emitted radiation will not be isotropically distributed about the source. This report describes a calculation by the Monte Carlo method to find the energy and angular distributions of photons emitted from a cylindrical or spherical encapsulated source. Computed results are compared with experimental observations of energy and angular distribution, and show good agreement. Calculated spectra for typical cylindrical sources of Co-60 encapsulated in iron are given. Author
