Radial Cutoff LET and Radial Cutoff Dose Calculations for Heavy Charged Particles in Water

Abstract

A model has been presented to calculate radial energy deposition around the trajectory of a heavy charged particle in water. The model originates from the basic concept of knock-on collisions and glancing collisions in stopping-power theory. Energy deposition by diffusive motion of low-energy electrons has been included in the calculation. Available experimental data agrees reasonably well with the results of the present model.
