摘　　要：为了探讨辐照对大田软海绵酸(OA)的降解效果,采用60Co-γ射线辐照降解水溶液和扇贝组织中的OA,基于ELISA法分析辐照剂量、OA初始浓度以及OA所处体系对其降解率的影响。结果表明,OA初始浓度越低、辐照剂量越大,辐照降解率越高。不同体系中辐照降解率的顺序为:水溶液体系的OA>肌肉组织体系的OA>肠道组织体系的OA>胰腺组织体系的OA。研究证实辐照技术可用于去除饮用水中的OA毒素,但去除扇贝等水产品中的OA毒素尚有困难。本研究为OA的去除提供了参考。To investigate the degradation effect of radiation on Okadaic acid（ OA）,Cobalt 60 gamma ray（^60Co-γ） was used to degrade OA in water and scallops.ELISA was used to study some influence on the degradation rate,such as irradiation dosage,the initial concentration of OA and dissolution system.The result showed the degradation rate increased with the the increase of irradiation dosage,and decreased with the increase of the initial concentration of OA.In addition,degradation rate is also related to dissolution system.The degradation rate from high-to-low is OA in water,OA in muscle,OA in intestine and OA in hepatopancreas.The study confirmed that the irradiation technique can be applied to remove OA in water,but it is difficult to remove OA in aquatic products,such as scallops.The result of the study provides reference for the OA removed
