摘要

作为物理实验1系列实验的一部分，部署了一套测量系统，该系列实验涉及在美国内华达州国家安全场址（NNSS）的地下洞穴中引爆化学炸药和放射性核素示踪剂。其中一种放射性核素示踪剂127Xe在爆炸后从安全壳中释放出来，并在大约3.5公里外的桑拿QB取样器上检测到。该系统使用β - γ符合探测器系统来测量与核爆炸监测相关的氙的裂变产物放射性同位素。在这项工作中，我们使用符合测量数据来分析和解释桑拿QB系统的结果，计算测量的127Xe活性浓度(s)。

Analysis of 127Xe tracer measurements using a net counts method

A suite of measurement systems were deployed as part of the Physical Experiment 1 series of experiments, which involved detonating chemical explosives along with radionuclide tracers in an underground cavity, at the Nevada National Security Site (NNSS) in the United States. One of the radionuclide tracers, ¹²⁷Xe was released from the containment following the explosion and detected on a SAUNA Q_B sampler situated approximately 3.5 km away. The system uses a beta-gamma coincidence detector system to measure fission product radioisotopes of xenon relevant to nuclear explosion monitoring. In this work we use the coincidence measurement data to analyse and interpret the results from the SAUNA Q_B system, to calculate the measured ¹²⁷Xe activity concentration(s).

期刊介绍： The Journal of Environmental Radioactivity provides a coherent international forum for publication of original research or review papers on any aspect of the occurrence of radioactivity in natural systems. Relevant subject areas range from applications of environmental radionuclides as mechanistic or timescale tracers of natural processes to assessments of the radioecological or radiological effects of ambient radioactivity. Papers deal with naturally occurring nuclides or with those created and released by man through nuclear weapons manufacture and testing, energy production, fuel-cycle technology, etc. Reports on radioactivity in the oceans, sediments, rivers, lakes, groundwaters, soils, atmosphere and all divisions of the biosphere are welcomed, but these should not simply be of a monitoring nature unless the data are particularly innovative.
