- •
Up to about 60% of 137Cs was desorbed for 139 days in dilute KCl media.
- •
The fixation of Cs with high concentrations of K+ was alleviated with time.
- •
The desorbed fraction of 133Cs was much smaller than that of 137Cs.
- •
Desorption of 137Cs from the slowest sites was estimated to be in the order of years.
