摘要

目的对进口食品是否受到核电站泄漏污染进行快速筛选。方法应用减钾总β放射性测量方法对米面制品、奶粉进行检测,并测试了锶、铯的回收率,计算了探测下限。结果 12个进口米面制品和15个奶粉结果均低于探测下限。结论和国家标准方法相比,该方法效率高,不需要放射化学实验室,适合出入境实验室进行筛选检验。
        Objective To screen the imported food to see if it is polluted by the nuclear power plant leak. Methods Apply the excluding K gross β radioactivity method to detect the rice products and milk powders,test the recovery of Sr,Cs and calculate the LD. Results The results of 12 imported rice products and 15 imported milk powders were lower than the LD. Conclusion Compare the GB methods,the efficiency of this mothed is high. It needn't radiochemistry lab and fits for the screen test by CIQ lab.
