Tl. Ku et al., ASSESSING IN-SITU RADIONUCLIDE MIGRATION FROM NATURAL ANALOG STUDIES - RESPONSE TO MCKINLEY AND ALEXANDER (1996), Radiochimica Acta, 80(4), 1998, pp. 219-223
McKinley and Alexander (1996) criticized the model formulation of Ku e
r al. (1992) that described the use of naturally occurring U-Th series
disequilibria in rock-water systems for evaluating the in situ retard
ation of radionuclide migration. Many of these criticisms appear to re
sult from a misunderstanding of the model development and the formulat
ion of the rock-water exchange terms. We present a clarification of th
e issues they have raised.
