Measurements of the spatial patterns of environmental radionuclides can be used to measure soil erosion and sediment deposition on the landscape. This is the only technique that can be used to make actual measurements of soil loss and redeposition quickly and efficiently to design programs to conserve the quality of the landscape. Over the 60+ years since this first nuclear weapons test, much research has been done to understand the movement and fate of radionuclides in the environment. This paper presents a history of the development of techniques for the application of environmental radionuclides to studies of soil erosion, soil redistribution, and sediment deposition. A recent bibliography with over 3500 references demonstrates the widespread use of radionuclides for measuring erosion and sediment deposition.
