    摘要: An ionizing radiation-resistant polycarbonate resin composition comprising 0.1 to 10 parts by weight of an organic compound having one carbon--carbon unsaturated double bond forming a non-bonding orbital in the molecule based on 100 parts by weight of a polycarbonate resin, and a medical part comprising the same. The polycarbonate resin composition and the medical part comprising the same exhibit less deterioration of color and physical properties even when irradiated with ionizing radiation for sterilization, and are, therefore, useful as a medical part material and a medical part.
