| 摘 要： | 采用积分电流电离法测氡结果表明；当氡气剂量很低时，在给定时间内将十分微弱的电流积分，大大地提高了测定的灵敏度，可测得剂量为１Ｂｑ以下的氧气，与常用的ＦＤ－１２５氡钍分析仪的比较实验数据相对误差不超过５％．

| Abstract: | The experimental results of Rn determination by the ionizing method with integrated ciruit are presented. The sensitivity of Rn determination could be greatly improved by integration of weakly ionizing current at very low concentrations of Rn and within the given experimental period. Experimental results indicated that sensitivity would be 1 Bq dose of Rn. Relative error was less than 5% in comparison with that of the FD-125 Rn analyzor. |
