摘要
本文探讨Model 10 2 7连续测氡仪测量室内氡浓度的方法。用两台仪器对一房间内氡浓度在不同情况下进行近一个月的测量后 ,得出以下结论 :仪器操作简便 ,测量结果稳定 ;仪器处于DISABLE(数字显示关闭 )状态所测氡浓度高于ENABLE(数字显示开启 )状态测量氡浓度 ;测量结果表达方式有两类 ,即氡浓度总平均值和美国环保局推荐平均值 ,多点比较测量应采用同一类氡浓度 ;仪器连续测量时间不得少于 2 4h ,最好为 4 8h或更长 ;本次所测房间氡浓度平均值为 92 5Bq/m3。
The method to measure radon indoor using model 1027 continuous radon monitor was introdueed After measuring for nearly a month,it was concluded that: The radon concentration in ventilation was lower than that without ventilation ;Radon concentration in DISABLE was higher than that in ENABLE; Same kind of concentration should be employed during a serial test ;Aud a typical test should continued for a period of two or more days
