Abstract

Measurements carried out recently with surface labile layers of the estuarine sediments have indicated remarkable dis-equilibrium between234U and238U activaties. The234U/238U activity ratios on the surface of the sediments collected from Mindola estuary of Gujarat State in India have been found to vary in the range of 1.12 to 1.43 while235U/238U activity ratios lie in the range of 0.045. On removing the labile layers and leaching uranium from the core of the sediment particles gave, an equilibrium ratio of 1.00 for234U/238U. There is however no change in the activity ratios of235U/238U.
