Contribution of secondary electrons to radiation fields produced by pion beams

PDF Version Also Available for Download.

Description

In recent years many biological and therapeutic studies have been done with a variety of high-energy particles. Although the theoretical and experimental application of collision cross sections for low-energy particles (less than or equal to 20 MeV) to microsodimetry continues to be a major area of interest, relatively little effort has been devoted to the application of such cross sections to a description of the interaction of high-energy particles in tissue. This article presents an approach based on existing models which is used to describe the interaction of energetic, fully stripped charged particles in biological materials on an event-by-event basis. ... continued below

Description

In recent years many biological and therapeutic studies have been done with a variety of high-energy particles. Although the theoretical and experimental application of collision cross sections for low-energy particles (less than or equal to 20 MeV) to microsodimetry continues to be a major area of interest, relatively little effort has been devoted to the application of such cross sections to a description of the interaction of high-energy particles in tissue. This article presents an approach based on existing models which is used to describe the interaction of energetic, fully stripped charged particles in biological materials on an event-by-event basis. As an application of the technique, contributions of delta rays produced by high-energy (W approx. = 540 Mev/amu, ..beta.. approx. = 0.8) pion beams to the energy deposited area calculated. The results are compared with new experimental microdosimetric spectra obtained with both walled and wall-less counters.
