This work presents the results from simultaneous measurements of 222Rn in soil-gas by compact discs (CDs) and diffusion chambers. The measurements were performed in three terrains with high, medium and low 222Rn-in-soil-gas concentrations. Good correlations between the CD measurements and the reference diffusion chamber measurements are observed. The results indicate that it is important to apply temperature correction in the CD measurements, in order to account for the actual temperature during the exposure of the CDs in the soil.
这项工作展示了通过光盘（CD）和扩散室同时测量土壤气体中222Rn的结果。测量在土壤气体中222Rn浓度高、中、低的三种地形中进行。观察到CD测量结果与参考扩散室测量结果之间具有良好的相关性。结果表明，在CD测量中进行温度校正很重要，以便考虑CD在土壤中暴露期间的实际温度。
