In-situ measurement of fallout radionuclides (137)Cs and (210)Pb(ex) has the potential to assess soil erosion and sedimentation rapidly. In this study, inventories of (137)Cs and (210)Pb(ex) in the soil of Inner Mongolia grassland were measured using an In-situ Object Counting System (ISOCS). The results from the field study indicate that in-situ gamma-ray spectrometry has the following advantages over traditional laboratory measurements: no extra time is required for sample collection, no reference inventories are required, more economic, prompt availability of the results, the ability to average radionuclide inventory over a large area, and high precision.
原地测量沉降放射性核素（137）铯和（210）钋（外照射）有潜力快速评估土壤侵蚀和沉积情况。在本研究中，使用原地物体计数系统（ISOCS）测量了内蒙古草原土壤中（137）铯和（210）钋（外照射）的存量。实地研究结果表明，与传统实验室测量相比，原地伽马射线能谱法具有以下优点：无需额外时间进行样品采集，无需参考存量，更经济，结果可迅速获得，能够在大面积上对放射性核素存量进行平均，且精度高。
