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
