| 中文摘要: |
| 讨论多时间间隔分析方法(又称TIA方法)和延迟符合法同时测量10 Bq的220Rn标准源,两者为相同实验平台,采用卢卡斯氡探测器(FD-125)对220Rn标准源进行流气式测量,改变软件实现两种不同数据处理方法.实验结果表明,多时间间隔分析法在测量低浓度220Rn时更加准确. |
| 英文摘要: |
| This article focuses on the time interval analysis(TIA method) method and delay coincidence method at the same time measuring 10 Bq of 220Rn standard source,both for the same experimental platform and conditions.Lucas detector(FD-125) was applied to flow-through measure the standard 220R,two different data processing methods were established by changing the software.It can be seen,the time interval analysis is more accurate than delay coincidence for measuring the low 220Rn. |
