| 摘 要： | 论述了数字化气氡仪器SD-3A型自动测氡仪在观测中值得注意的几个问题,特别要注意①气氡观测数据在使用前要经过气温和气压的改正;②闪烁室进水、受到其他气体的污染、补充气体不及时等对观测结果影响是很明显的;③闪烁室在用空气和无水酒精清洗后测值的恢复有一个过程;④仪器标定前应用无水酒精对闪烁室进行清洗,才能提高标定的准确性.

| Abstract: | Several problems that should be paid attention to during the observation of Radon Detector with digital instrument of type SD-3A are discussed in the paper. They are (1) air temperature and air pressure corrections are necessary before the radon measurement data being used; (2) the measurement errors resulted from water getting into scintillant cell, contaminated by other gas and failing to replenish gas in time are obvious; (3) the process of measurement precision recovery after cleaning the scintillant cell with gas and anhydrous alcohol will last for awhile; (4) for improving the precision of instrument calibration, the scintillant cell should be cleaned with anhydrous alcohol before the calibration. |
