Influence of energy straggling on the shape of neutron-produced single event spectra

Summary The influence of energy straggling on the shape of single event spectra produced by neutrons in volumes equivalent to very small spherical biological systems was investigated by simulation of the interaction processes with a Monte Carlo calculation.The results show that the effect of energy straggling already becomes noticeable for fast neutrons of 6 MeV at equivalent sphere diameters of 1.0 m and increases in importance with decreasing volume size.
