摘　　要：经测定，γ射线杀灭液体培养基、牛奶、糕干粉与牛肉末中单核细胞增生李斯特氏菌的Ｄ１０值分别为０．５５、０．７５、１．０３与１．１１ｋＧｙ。该菌在不同介质中对辐射的抗性不同。The results of measurement indicated that the D 10 values of γ-rays for killing Listerella monocytogenes in liquid culture medium, cow milk, sweetened rice flour and minced beef were 0.55, 0.75, 1 03 and 1 11 kGy respectively. The bacteria had different radioresistance in different media, therefore, different ways should be used for calculation of disinfecting radiation dose.
