新型放射性气溶胶连续监测仪的实验研究

Study of an Advanced Continuous Radioactive Aerosol Monitor

主要介绍一种新型α/β放射性气溶胶连续监测仪,对其在天然及有人工放射性两种场所中的实验数据,用累积式测量数据处理方法分别进行了三次不同的数据处理,并对其处理结果进行了研究和评述。在对天然氡钍场所的实验数据处理中,分别给出了三次处理的"灵敏度"(判断阈和探测限)指标,并对这些指标也进行了研究和评述。

An advanced continuous α/β radioactive aerosol monitor are stated. For a set of data monitored in nuclear facility and a set of data monitored in background air, three different monitoring results obtained on the basis of accumulation processing methods are evaluated and discussed respectively. To the later set of data, the monitoring sensitivity （decision threshold and detection limit） corresponding to three methods is compared and illustrated.
