Abstract :

Awide variety of polymer material effects are induced by thermal annealing. The effectiveness of a particular material is found to vary not only with the thermal annealing but also with the type of ion and its energy and ionization rate i.e., with the nature of the ion tracks. Moreover, a significant transformation of the registration properties of charged particles in these polymer materials is induced by thermal annealing. An overview is presented of some thermal annealing experiments which were carried out on the high polymer material poly allyl diglycol carbonate PADC (a form of CR-39) exposed to different radioactive sources. This work highlights the fact that the annealed PADC films are highly sensitive to the fission fragments and particles heavier than alphas (z ≥ 6), but not to alpha particles. Recent experiments have been performed at the Nuclear Physics Research Laboratory, University of Benghazi. These show, without any doubt, that the response of thermally treated PADC material to charged particles is not always restricted to heavy ions with high ionization rates; particles with low ionization rates is somewhat restricted.
