Chain terminations in the decomposition reactions of chloroethylenes in air through the deposition of alkylperoxy radicals on the wall of an irradiation vessel

The decomposition reactions of chloroethylenes in air were studied for electron beams and 60Co γ-rays at different dose rates using irradiation vessels having different S/V ratios. The chain termination of their decomposition reactions involves the bimolecular reactions of alkylperoxy radicals (RO2
- ) for high dose-rate irradiations, while it involves the deposition of RO2
- on the wall of the irradiation vessel beside this bimolecular reaction for low dose-rate irradiations, and/or irradiations using vessels having larger inner surface area to volume ratio.
