摘 要 ：摘要：概述了辐照技术在控制食品真菌毒素、农药、兽药、渔药等方面残留污染的研究现状，并就辐照降解效果、降解机理、降解产物及毒性等内容加以阐述，总结出导致食品污染物降解的原因主要是由于辐照产生的自由基作用于物质结构中键能较低的位点，生成使毒性减小或增大的降解产物，并分析了辐照技术在食品污染物残留控制方面的局限性以及发展方向。

Abstract:Abstract：The current state of the researches of irradiation technology on controlling food mycotoxin, pesticide, veterinary drugs and fishery drugs residue was summarized. And the degradation rate, mechanism, products and toxicities of food contamination were expatiated. The free radical from irradiation attack the site of weaker bond, and the less or more toxic substances were produced, which lead to the degradation of the food contamination.The limitations and future application of irradiation technique on controlling food contamination were also analyzed．
