The effect of salinity on the concentrations of radium and thorium in sediments
The effect of salinity on the sorption behaviour of radium and thorium has been studied with the aim of assessing the suitability of the 226Ra/232Th activity ratio (AR) as a tracer in saline waters. Radium has been reported in the literature as being highly mobile in saline water, and easily desorbed from sediments, whereas thorium is believed to remain tightly bound. Results of analyses of bed sediments from an inland river system with a record of past regimes of high dissolved salt...[Show more]
