Abstract

Particle penetration phenomena are intrinsically statistical in nature. It is extremely unlikely that two particles penetrating a material medium at different times will undergo the same sequence of collision events. This applies even to ideal experiments with a well-collimated, monochromatic particle beam hitting a highly homogeneous target material with a uniform thickness. The energies and directions of motion of penetrating particles, as well as their charge and excitation states, will differ shortly after they hit the target. The same is true for the radiation effects they generate, such as excitation, ionization, and relocation of target atoms, and nuclear or chemical reactions. In brief, whatever quantity you find appropriate to measure, you will find fluctuations, and these fluctuations will not go to zero if you increase the number of particles in the beam.
