摘　　要：为保障食品食用安全,针对合肥市多家超市海带样品,通过放射性检测仪检测辐射水平,采用单因素协方差分析扣除产地影响,两因素裂区分析探讨减害方法,配对t检验比较效果,探讨降低食用海带有害放射性的简单易行的措施.结果表明:仅用清水浸洗便能有效降低海带放射性污染,温水浸泡、适当延长浸洗时间及多次换水,均能改善减害效果;海带本底辐射水平约0.5 Sv·hr^(-1)以上,清洗能降低到0.3 Sv·hr^(-1)以下,有效保证食用安全.To ensure the security of food, in this paper the authors studied the seaweed samples from several supermarkets in Hefei city, using the radioactivity detection to test the different radiation levels of different cleaning measures before and after processing. Single factor analysis of covariance was applied to deduct the origin effect, two-factor split plot design was conducted to discuss the harm reduction method, paired t test was applied to compare the results, to discuss the simple measures of reducing edible seaweed harmful radioactive. Results showed that water baptism only can effectively reduce the seaweed radioactive contamination; warm water soak, extending baptism time and changing water for many times, could all improve the effect of harm reduction; seaweed background radiation level was above 0. 5 μSv · hr-1, cleaning can reduce to below 0.3 μSv · hr-1 which effectively ensure the edible safety.
