We investigate the properties of the radial distribution of energy deposited by ions, calculated using a random walk approach, which is an important analytical tool for solving transport problems. This investigation is motivated by the desire to understand the range of applicability of the random walk approximation for problems related to radiation damage assessment. We study the radial dose at small and moderate distances and compare our results to the results of Monte Carlo simulations.
