退役核设施环境植物中氚的分析

Analysis of Tritium in Environment Plant Samlpes Around Nuclear Facilities

摘要: 建立了一种适用于退役核设施环境植物样品中氚快速分析的方法，在建立快速制样装置的基础上，对场所退役源项调查过程中的含氚植物样品进行了分析。结果显示：建立的制样装置在实际样品处理中，分析时间与传统方法相比缩短2～3 h，回收率＞75%。以上结果表明，所建立的方法适合退役过程中大量植物样品中氚的分析。

Abstract: A method for the measurement of tritium in environment plant samples around nuclear facilities was introduced. The method was applied to the analysis of the environment plant samlpes during the fountainhead investigation of some Nuclear Facility.The results indicated that the analysis time was shortened by 2-3 h in comparison with the conventional method and the recovery was more than 75%.This mehtod was suitable for the measurement of tritium in plants during nuclear facilities decommissioning.
