摘要：

浓缩氙天文台（EXO）将搜寻136氙的双β衰变。我们报告了对EXO-200（EXO实验计划的第一阶段）建造中使用的各种原材料和成品中放射性杂质痕量浓度进行系统研究的结果。所采用和描述的分析技术包括直接伽马计数、α计数、中子活化分析和高灵敏度质谱法。

英文摘要：

The Enriched Xenon Observatory (EXO) will search for double beta decays of 136Xe. We report the results of a systematic study of trace concentrations of radioactive impurities in a wide range of raw materials and finished parts considered for use in the construction of EXO-200, the first stage of the EXO experimental program. Analysis techniques employed, and described here, include direct gamma counting, alpha counting, neutron activation analysis, and high-sensitivity mass spectrometry.
