γ-Ray (and electron) induced annealing of nuclear tracks in polymeric detectors
Abstract
Energy loss profiles for secondary electrons and γ-rays are discussed and the interactions of γ-rays with the activated species within the core of a nuclear track investigated. Based on an electron-hole trapping mechanism experimental values for the activation energies of annealing for nuclear tracks in the range of 0.26 to 0.5 eV have been obtained. These compare favourably with theoretical expectations. The consequences of variations in the detection sensitivities of such detectors are discussed.
