Abstract
The effect of gamma-irradiation, with doses from 10(2)-2 x 10(3) kGy, On the dielectric properties of solid-state collagen was studied. The temperature dependence of the constants epsilon' and epsilon'' reveale d a decrease in the denaturation temperature with increasing dose of i rradiation. Dielectric dispersion observed in the frequency range 10 H z to 10 kHz was suggested to be due to Maxwell-Wagner-Sillars polariza tion. In addition, an increase in the irradiation dose resulted in inc reasing activation energy of bovine achilles tendon collagen.
