Tutorial - How Radiation Affects Polymeric Materials
M. Al-Sheikhly, and A. Christou
Radiation-induced degradation of polymeric materials proceeds mainly
through free-radical oxidation mechanisms. The radiolytically produced
free radicals react with the molecular oxygen to produce the corresponding
peroxy radicals. The production of peroxy radicals initiates oxidation
processes which then lead to degradation. The tutorial explains the
mechanisms of radiation-induced oxidation & analytic techniques that
can be used to measure it.
