经测定，５．０Ｍｒａｄ剂量电离辐射可将染于骨移植材料上的金黄色葡萄球菌、枯草杆菌黑色变种芽胞与蜡状杆菌芽胞完全杀灭；１００ｍｇ／Ｌ环氧乙烷气体作用２０小时，亦可达到灭菌效果。随环氧乙烷浓度增大，灭菌所需时间缩短。
It was determined that 5.0Mrad dose ionizing radiation could completely kill Staphylococcus aureus, Bacillus subtilis black mutant spores and waxy bacillus spores infected on the bone graft material; 100mg / L ethylene oxide gas for 20 hours and also Can achieve sterilization effect. As the ethylene oxide concentration increases, the time required for sterilization shortens.
