Abstract
The manner in which voids affect both the range and the energy deposition of energetic charged particles in irradiated metals has been investigated. Calculations of energy deposition for 5 MeV Cu++ ions and 1 MeV protons incident on Fe indicate uncertainties in these quantities that increase with penetration distance. Mass density corrections adequately account for the presence of voids, except at the end of range where the contribution of void-induced straggling can be significant. The extension of the average range in these samples can be appreciable, depending upon the relationship between swelling and dose.Keywords
