ABSTRACT=This paper presents measurements of cesium-137 ( 137 Cs) in the Qaidam Basin during 2019 with 39 soil samples across the landscape. The aim here is to use the results of 137 Cs inventories for the Qaidam Basin to subsequently estimate soil wind erosion.The 137 Cs inventoriesactivities in the surface soil vary from lower limit detection (LDD) 0 to 1072 Bq m -2 , with a mean of 266 Bq m -2 . Overall, the 137 Cs inventoriesactivity in the Qaidam Basin decreases from southeast to northwest. The highest 137 Cs inventoriesactivity was found in farmland, and the lowest was found in Gobi. Wetlands had higher 137 Cs inventoriesactivity than their neighboring sites.
