Abstract
The optical absorption spectra of polyvinyle chloride, PVC, doped with
Cd and Pb is presented. The effect of gamma radiation doses in range
of 2-200 Mrad on the fundamental absorption edge lambda(g) was determi
ned. On the basis of quantitative analysis of obtained data, the calcu
lated absorption coefficient, alpha, the absorption index, K, and the
optical energy gap E(opt.) were found to be radiation and dopant depen
dent. The results are discussed on the basis of the radiation induced
degradation of PVC.
