Invention of irradiated polymeric composites as nuclear ray counters

Dhameer A. Mutlak

Abstract

This research demonstrates that gamma radiation could cause changes in the absorbance spectra of polymers. The study examines the feasibility of the effect of gamma rays on some physical properties, the degradation and cross-linking reactions resulting from irradiation was examined. The samples of pure epoxy were irradiated for (1,2,3,4,5,6 months). Observed changes in the color of epoxy composites, color varied from yellow up to dark brown gradually as a result of different radiation doses effect on the expose epoxy composites. The change in the color of the overlays as a result of nuclear radiation can be used as an indicator of the extent of exposure in time and its clear effects on its properties due to exposure to radiation. Gamma cell 900 was used in this study to irradiate all the samples. A series of composites has been prepared by adding lead powder with different masses to the epoxy resin. The degradation process slowed when the samples were exposed to radiation for longer time periods.
