Space radiation may affect the structural integrity of biological tissues through damage to collagen, a critical protein in connective tissue. This study examined radiation effects on collagen structure and mechanical properties. Results showed dose-dependent degradation of collagen organization and strength, suggesting potential concerns for tissue health during long-duration spaceflight and the need for protective strategies.
Ionizing radiation exposure significantly altered collagen structure and mechanical properties in tissue samples. Radiation-induced damage accumulated with increasing dose, affecting collagen fibril organization. Mechanical testing revealed decreased tensile strength and elasticity in irradiated samples. Structural analysis using microscopy showed disruption of collagen cross-linking patterns. These findings have implications for tissue engineering and radiation protection in space environments.
