Review of information on hydrology and radionuclide migration at the Nevada Test Site 1976--1988, and annotated bibliography

“…The maximum effect occurs within alteration zones containing clinoptilolite and montmorillonite, suggesting that these minerals effectively remove bivalent cations from the system. Whitfield, M.S., Jr., W. Thordarson, and E.P. Eshom.…”
