Over 40 soil gas samples were collected both in post-industrial areas as well as in undisturbed areas in the region of Kvarntorp, Sweden. Radioxenon (¹³³Xe) was detected in 15 samples and radioargon was detected in 7 from 10 samples analysed. The concentration of radioxenon and radioargon in soil gas ranged up to 109 mBq/m³ and 19 mBq/m³, respectively. During sample collection other soil gases such as radon, CO₂ and O₂ were also measured and soil samples were taken along with dose rate measurements. The field experiment presented here shows that it is possible to detect naturally occurring radioxenon and radioargon in soil gas simultaneously.

在瑞典克瓦恩托普地区的工业化后地区和未受干扰的地区均采集了40多种土壤气体样品。在分析的15个样品中检测到了放射性氙（¹³³ Xe），在分析的10个样品中有7个检测到了放射性氩。土壤气体中放射性氙和放射性氩的浓度分别高达109 mBq / m ³和19 mBq / m ³。在样品采集过程中，还测量了其他土壤气体，例如ra，CO ₂和O ₂，并与剂量率测量一起采集了土壤样品。此处进行的现场实验表明，可以同时检测土壤气体中自然存在的放射性氙和放射性氩。
