Boltzmann Transport Model Assumptions
The Boltzmann Transport Equation (BTE) is the governing
equation which describes the macroscopic behavior of radiation particles (neutrons, photons, electrons, etc.) as they travel through and interact with matter
A particle (photon, …) is a point particle moving in straight lines between collisions. Particles (photons, …) interact with matter through binary collisions and the nuclei are distributed randomly: collision probability per unit distance is constant The Linear Boltzmann Transport Equation describes the mean behavior of radiation Linearity: No particle-particle interactions isotopic makeup of material constant
