Abstract
It is well known that the addition of small amounts of certain chemical additives to CR-39 will effect changes in its sensitivity, response and surface characteristics. We have studied the effect of adding small amounts of antioxidants to the monomer before casting. Stacks consisting of three types of CR-39 plastic were exposed to different energetic ions from proton through 56 Fe in order to study the track response properties. Response of each CR-39 type was investigated, covering a wide LET, Z and β region. We have also shown that the most sensitive of these materials registers tracks of relativistic boron ions and 16 MeV protons at normal incidence.
