Abstract
This study presents the temporal and spatial variability of 234U/238U activity ratios in the Shu River and provides interpretation to explain the downstream changes of uranium and the 234U/238U activity ratios in the study area. The positive linear correlation (R2 = 0.98, p < 0.001) between uranium concentration and specific electrical conductance is consistent with rock weathering and leaching as the major contributor of dissolved uranium in the studied area of the river. The 234U/238U activity ratio ranged between ~1.6 in the upper reaches of the river to ~1.15 furthest downstream. Activity ratios at specific sampling points do not show significant seasonal variability.
