The radiation propagation was done with the NOVICE* code (Jordan 1976) using its solid angle sectoring/3-dimensional adjoint (reverse) Monte Carlo transport capability. The use of the adjoint method, in which particles are followed backward from the target to the observatorys exterior, greatly increases the calculation efficiency compared to a forward Monte Carlo code because only particle trajectories that interact with the target are tracked (Desorgher 2010). NOVICE also interfaces with Computer Aided Design (CAD) models, allowing complex shielding geometries such as observatories and instrumentation to be analyzed.
