Dose Rate Effects in Polymer Materials Irradiated in Vacuum

Loss of chemical bonds induced by high doses of γ-radiation in a PADC polymer film: The influence of dose and dose rate on radiation chemical yields

“…The decrease of dose rate lowers thus radiation chemical yields for destruction of C=O and C-O-C bonds. The so-called dose rate effects (DRE) in polymer properties under irradiation in an oxygen environment are known to be very significant and connected with chain reactions of oxidizing radiation destruction initiated by radiolysis species of radical type (Briskman et al, 2004). DRE yields either from physical or chemical aspects.…”
