The Lawrence Livermore National Laboratory is to conduct an in situ test of radionuclide migration in fractured granite. Radionuclides are to be injected into a fracture in the Climax Stock of the Nevada Test Site, then transported by fluid motion and sub...
An understanding of the transport of radionuclides in carbonate minerals is necessary to be able to predict the fate of (and potentially remediate) radionuclides in the environment. In some environments, carbonate minerals such as calciate, aragonite, dol...

The purpose of this report is to provide a clearer perspective of the impact of radionuclides in soil and groundwater, particularly for those not well-versed in soil science, hydrology, and geology. Through nuclear waste disposal or accidents, radionuclides come in contact with soil and groundwater. Man is exposed to radiation as a result of movement (or ...
