Abstract
Aflatoxin B1 in a 5-micrograms/ml water solution was sensitive to ionizing radiation. Inactivation was assayed by the Ames microsome mutagenicity test and confirmed by thin-layer chromatography. Destruction of aflatoxin B1 had already begun at 2.5 kilograms (kGy; 1 kGy = 0.1 Mrad), but a dose exceeding 10 kGy was necessary for total destruction.
摘要
5微克/毫升水溶液中的黄曲霉毒素B1对电离辐射敏感。通过艾姆斯微粒体诱变性试验测定其失活情况，并通过薄层色谱法进行确认。黄曲霉毒素B1在2.5千戈瑞（1千戈瑞 = 0.1兆拉德）时就已开始被破坏，但完全破坏需要超过10千戈瑞的剂量。
