GAMA RADYASYONU İLE STERİLİZE EDİLMİŞ KORTİKAL KEMİĞİN DİNAMİK YÜK ALTINDA MEKANİK DAVRANIŞININ İNCELENMESİ

The effect of gamma radiation on the dynamic mechanical properties of cortical bone was accessed in this study. The cortical bone samples were divided into two groups: an untreated control specimens and specimens subjected to gamma radiation sterilization. A dose of 30 kGy was used to sterilize the bone samples. Unlike the quasi-static mechanical tests, dynamic mechanical test have shown that gamma-irradiated cortical bone has increased yield stress, ultimate stress and modulus of elasticity. Statistical differences were determined by the Mann–Whitney test at a significance level of P<0.05
