The mechanism of 234U 238U activity ratio enhancement in karstic limestone groundwater
(Elsevier B.V., 1993-01-05)
Experimental etch/leach of Carboniferous Limestone gravels on a laboratory time-scale has demonstrated that 234U 238U activity ratios (AR's) greater than the radiochemical equilibrium value may be generated on short ...
