Abstract
This paper presents a comprehensive analysis of the effects of radiation and combined exposure on the structure and properties of bone tissue, with a particular emphasis on changes in the collagen matrix. A mathematical model has been developed describing changes in interfibrillar distances in collagen, enabling a quantitative relationship between the radiation dose and the level of protein matrix degradation. It was found that combined sterilization allows reducing the radiation dose to 12 kGy, while maintaining the structural integrity of collagen and the mechanical properties of bone material. A model of collagen degradation under the influence of radiation is proposed, linking the dose load with a change in intermolecular distances; a quantitative correlation between the parameters Δr (according to the model) and structural changes in collagen was established; the possibility of reducing the radiation dose while maintaining the sterilizing effect through ozone pretreatment has been experimentally demonstrated.
