Physical Properties of Silk Fibroin Fibers Irradiated with Gamma Rays

We gamma-irradiated silk fibroin fibers at a dose of 25 kGy and measured the changes in their tensile properties and hue. Irradiation reduced both the breaking strength and the elongation at breakage by up to 10%, and yellowed the fibers, but the degree of crystallinity was almost unchanged.
