Abstract
As the number of nuclear facilities increases, larger amounts of the actinide elements-neptunium, americium, and curium-will be generated. Because these elements are radiotoxins, these releases may have public health implications. Investigations were undertaken to observe the physical processes controlling diffusional movement of the actinides in soil. When representative soils were shaken with neptunium, americium, and curium in distilled water, it was found that much of the americium and curium, and some of the neptunium, was bound to soil particles having colloidal dimensions. Effective distribution ratios indicated that increasing retention of the actinides by most of the soils continued for 4-6 MO. Furthermore, the proportion of actinide retained by potentially diffusible soil particles decreased with time.
