If one considers the reflection/refraction of a steady stream of photons moving in the positive x direction and striking an n1=1 versus n2 interface along the y axis at x=0, one may immediately write a conservation of photon number equation i.e. N(in

The possibility of expressing the total particle and energy reflection coefficients of low-energy photons in the form of universal functions valid for different shielding materials is investigated in this paper. The analysis is based on the results o
