摘要
2021年,新疆库尔勒新43泉开展SD-3A和BG2015R气氡仪串联同步对比观测,选取2套气氡仪当年观测资料,采用快速傅里叶变换进行高频信号分析。结果显示:2套气氡仪观测数据一致性和同步性较好,呈相同变化趋势;二者均能较好记录到日潮、半日潮和三分之一潮等频段信号;BG2015R气氡仪观测平均值较SD-3A气氡仪低约10 Bq/L。分析表明,BG2015R气氡仪记录连续、稳定、可靠,能准确反映溶解氡含量的真实变化,可作为SD-3A气氡仪更新换代设备。
In 2021,synchronous comparative observation of radon detector SD-3A and BG2015R was carried out at Korla Xin-43 Spring in Xinjiang.Two sets of radon detector observation data in that year were selected,and high frequency signal analysis was carried out by fast Fourier transform.The results show that good consistency and synchronism of the observation data of the two sets of radon detectors and both of them showed the same trend of change;both of them can record the frequency band signals such as tidal,semidiurnal,and one third of the day well;the average value of the observation of BG2015R radon is about 10 Bq/L lower than that of SD-3A radon detector.The analysis shows that the BG2015R radon detector can record data continuously,stably and reliably,and can accurately reflect the real change of dissolved radon content,and thus this instrument can be used as an updated equipment for SD-3A radon detector.
