The Effect of Irradiation on Rheological and Electrical Properties of Collagen

Abstract

This paper describes the effects of irradiation on the rheological and electrical properties of a 7.7% mass fraction of native bovine collagen in water. The radiation dose was in the range of 0 - 500 Gy. Rheological oscillation measurements were done at temperatures of 10, 20, and 30 °C. There was a statistically significant dependency of storage and loss moduli on irradiation dose and oscillation frequency. There was no significant change in the electrical conductivity of collagen during oscillation movements or any dependence on irradiation dose.
