摘要
介绍了一种新型的氡及其子体连续监测仪,它采用特殊设计的静电高压收集衰变室(圆柱体筒)、专用泵取样气路系统以及入口过滤和探测装置、纯氡探测装置。含有两个探测器(测量氡子体的(?)20mm的硅探测器和测量氡浓度的(?)30mm金硅面垒探测器)。计数容量99999999;测量范围:氡浓度0-10MBq/m3,氡子体浓度0-1MBq/m3,氡子体α潜能浓度0-0.01J/m3。具有体积小、灵敏度高、响应时间快、操作方便、自动显示、数据存储、串口传输与打印、超阈报警等特点。能实时显示计数,并在设置的时间间隔内,仪器以两种方式给出氡浓度、氡子体浓度或总α潜能浓度。
A new radon and it＇s daughters continuous monitor is introduced in this paper. It is made of static high voltage collecting cylinder room,appropriative pump,samping system,filtrator,a silicon detector and a surface-barrier semiconductor detector. It is a little volume,good delicacy ,ordinary operation,quicky response,automatically display,data memory,serial data transfer and print,give an exceeding alarm. It＇s counter capability is 99999999,radon metrical area 0--10M · Bq/m^3,radon,s daughters metrical area 0--1M · Bq/m^3, potential a energy of radon daughter 0-1M × 10^-3 J/m^3. It takes count of result in real-time.
