我们报告了为建造EXO-200双贝塔衰变实验而进行的系统测量活动的结果，以确定低放射性材料。这项运动的部分结果已经在EXO合作组织2008年的一篇论文中报告了。在这里，我们向公众发布自2007年以来收集的剩余数据。报告的数据是使用各种分析技术获得的。其测量灵敏度在该领域中名列前茅。EXO-200探测器的建造已经完成，第一阶段数据是从2011年到2014年获取的。探测器极低的背景隐含地验证了在建造过程中所做的测量和分析假设，并在本文中报道。
We report results from a systematic measurement campaign conducted to identify low radioactivity materials for the construction of the EXO-200 double beta decay experiment. Partial results from this campaign have already been reported in a 2008 paper by the EXO collaboration. Here we release the remaining data, collected since 2007, to the public. The data reported were obtained using a variety of analytic techniques. The measurement sensitivities are among the best in the field. Construction of the EXO-200 detector has been concluded, and Phase-I data was taken from 2011 to 2014. The detector’s extremely low background implicitly verifies the measurements and the analysis assumptions made during construction and reported in this paper.
