室内氡气浓度水平的测量使用井型NaI （Tl）检测器进行，可容纳含有10克活性炭的小瓶用于检测氡气。小瓶暴露3小时后，进行伽马射线能谱测定。用150 ~ 1360 keV的大能量窗研究了氡子代引起的计数数的相对增加。并与有源氡监测仪进行了比较。该工作提出了使用少量活性炭和井型NaI检测器测量氡浓度的可行性。D 2004 Elsevier BV版权所有
Measurements of indoor radon gas concentration levels were performed using a well-type NaI (Tl) detector accommodating vials containing 10 g of activated charcoal for the detection of radon gas. After the exposure of the vials and the elapse of 3 h, gamma-ray spectrometry was performed. A large energy window of about 150 to 1360 keV was used to study the relative increase in the number of counts due to radon progeny. Comparison of the method was made with an active radon monitor. The work presents the feasibility of use of a small amount of activated carbon along with a well-type NaI detector for the measurement of radon concentration. D 2004 Elsevier BV All rights reserved.
