WebThe radiation chemical yields are expressed in terms of G-values. G(scission), G(s), equals the number of main chain scissions produced per 100 eV of energy absorbed and G (cross-linking), G(x), the number of crosslinks formed per 100 eV absorbed. The G-value is a structure dependent constant similar to quantum efficiency in WebSurface modification by gamma irradiation method can answer these problems by generating free radicals that can induce chain scission or recombination, branching, or crosslinking.
