摘　　要：目的了解入境船舶载自境外的压舱水中放射性核素污染情况。方法采集入境船舶载自境外的压舱水样本,每艘次采集5 L,按照国家相关标准检测27种放射性核素。结果共检测了5艘次入境船舶载自境外压舱水样本,进行了27种放射性核素检测,其中5个样本检测到钾-40,浓度为12.33~20.29 Bg/kg,平均浓度为16.43 Bg/kg,是秦皇岛海域最高值的1.65倍;在1个样本中检出镭-226,浓度为0.52 Bg/kg,是秦皇岛海域最高值的61.18倍;其余25种放射性元素均未检出。结论应关注入境船舶载自境外的压舱水放射性核素的污染情况。Objective To determine the condition of the ballast water polluted by the radionuclides loaded from abroad in entry ships.Methods The samples of the ballast water(5 L per ship)in the entry ships loaded from abroad were collected.A total of 27 kinds of radionuclides in the water samples were detected according to the national standards.Results A total of 5 entry ships’ballast water samples were surveyed,27 kinds of radionuclides were detected.In which,^(40)K element was detected positive in 5 samples,and the concentration was 12.33~20.29 Bg/kg,the average concentration was 16.43 Bg/kg,which was 1.65 times of the peak value in Qinhuangdao sea areas.^(226)Ra element was tested positive in 1 sample and the concentration was 0.52 Bg/kg,which was 61.18 times of the peak value in Qinhuangdao sea areas.The other 25 kinds of radiocative elements were not detected.Conclusion It should be paid more attention to the radionuclides contamination in ballast water of entry ships.
