Abstrakt: In studying the effect of ionizing radiation on the properties of human Achilles tendon collagen fibres, the following parameters were analyzed: hydrothermal contraction temperature, module of elasticity, the number of cross-links, free and bound water levels, acids-soluble fraction content, and ultrastructure. With radiation doses of 2-10 Gy no changes in the collagen status were noted. An increased (from 5 to 25 Gy) radiation dose caused changes in physicochemical properties which was indicative of the formation, in the connective tissue collagen, of radiation-induced intermolecular cross-links stabilizing the biopolymer structure.
