SAUNA系统惰性气体氙监测数据的统计规律研究

Statistical Laws of Noble Gas Xenon MonitoringData from SAUNA System

在对CTBT放射性核素台站SAUNA系统有效监测数据进行分析的基础上,利用统计学方法对分析结果进行了初步研究,结果表明:4种惰性气体氙同位素133Xe1、31mXe1、33mXe和135Xe的最小可探测浓度和活度浓度均呈高斯分布,且133Xe活度浓度的高斯分布存在不同程度的右拖尾并呈指数衰减。

Based on analysis of valid monitoring data from SAUNA system,the statistical laws of analysis results are preliminarily studied.The result shows that the activity concentrations and the minimum detectable activity concentrations of the four xenon isotopes 133Xe,131mXe,133mXe and 135Xe from SAUNA system follow Gaussian distribution and the Gaussian distribution of 133Xe activity concentration has right tail with exponential decay trend.
