摘　　要：以左归丸粉为试材,着重研究了加速器(电子束)和钴源(γ射线)辐照杀菌效果。通过存活菌计数法确定了菌落总数、霉菌和酵母的D10值。结果表明:经电子束和γ射线辐照的左归丸粉菌落总数的D10值分别为2.602 kGy和2.597 kGy,霉菌和酵母的D10值分别为3.112 kGy和3.208 kGy。3个批次验证试验表明,左归丸粉辐照基本符合D10值规律。The sterilizing effect of electron beam and y-rays on Zuogui powder was studied by measurement of survival microorganism. The D10 value of electron beam and γ-rays irradiation for aerobic bacterial count was 2.602 kGy and 2.597 kGy respectively compared to 3.112 kGy and 3.208 kGy for mould and yeasts. The results in the current study suggest that the sterilizing effect of electron beam and γ-rays on Zuogui powder will comply with D10 rules.
