Makrofol FR 7-2 polycarbonate samples exposed to range 20-400 kGy dose of gamma radiation. The modulations created in optical properties and intrinsic viscosity (IV) of the Makrofol samples has been investigated. Further, difference in color and refractive index were performed. In range of 50-250kGy, the obtained crosslinking increases the IV and the average of molecular mass. Accordingly, non-irradiated samples displayed considerable color sensitivity for the irradiation. Color intensity increased by dose to 400kGy and results a raise of red and yellow intensities.
