Abstract
The quasi-steady variation in 234U 238U activity ratio has been determined along an idealised homogeneous one-dimensional aquifer in which the transfer of radionuclides from the aquifer material to solution occurs by both α-recoil and ion exchange. The results highlight the importance of considering these two effects in predicting the variation of 234U 238U activity ratios in a flowing system. In particular, it was shown that such ratios in old waters should achieve the moderate values indicated by measurements.
