title: Hit cross-sections in single target theory.
abstract: A theoretical single target, single or multi-hit model for the biological effect cross-section for charged particles and gamma rays is expressed in terms of the fundamental physical interaction cross-sections. The model allows for the chemical action of the fragments and includes correction for saturation effects. An interesting conclusion, based on very limited experimental evidence, is that there are prospects of constructing a new system of radiation dosimetry with only two significant parameters; the effective volume of the target and the concentration of events. No energy parameters are necessary.
