Abstract:

Models corresponding to an adult Rhesus Monkey and a simple analogue have been created in combinatorial geometry for use in Monte Carlo radiation transport calculations. The complex monkey phantom is based on anatomical measurements of a sectioned cadaver. Adjoint Monte Carlo calculations were performed to obtain the energy-and angle-differential adjoint fluence for the mid-head, mid-thorax locations in both phantoms and active marrow in the complex monkey phantom. The results have also been convoluted with free-field spectra for two TRIGA reactor exposure room configurations at the Armed Forces Radiobiological Research Institute, using the VCS code system. Comparisons are made between calculated and measured KERMA values in the simple phantom. Good agreement is obtained. However, it is found that good agreement cannot be obtained using simple scalar coupling.
