【摘要】 基于中国原子能科学研究院的串列静电加速器在我国建立了超高灵敏加速器质谱技术（ＡＭＳ）测定１２９Ｉ核素的方法，对我国可能受到人工放射性影响的环境中的１２９Ｉ进行了初步研究。结果表明，该地区１２９Ｉ含量比一般地区的含量明显偏高，其含量大小同取样地点相关。数据充分显示我国环境中１２９Ｉ核素含量也在增加。对于环境监测以及对于１２９Ｉ作为示踪剂在地球科学的应用而言，建立我国环境中的１２９Ｉ数据库是十分重要的。更多还原

【Abstract】 A study on ~129I in the environmental samples around the high radioactivity siteswas carried out. Samples were collected from the surface water and ground water.The ~129I in samples were measured using the AMS at the China institute of AtomicEnergy. The result showed that ~129I contents in samples collected at the vicinity ofhigh radioactivity sites were much higher than the content in the original rain water.更多还原
