BEHAVIOR OF RADIONUCLIDES ON ION-EXCHANGE RESINS
A study was made of the behavior of radionuclides on the ion-exchange resins used for decontaminating reactor cooling water. The nuclides were identified in cation, anion, and mixed-bed resin columns with a 20-channel gamma scintillation spectrometer. The results show that in all three columns, the concentration of the radioisotopes on the resin decreased with increasing bed depth. At the same time, the over-all half life of the retained materials simultaneously increased. Considerable variation with depth shows the shorter lived materials predominating near the surface, and the longer lived near the bottom of each column. Thus the removal efficiency of an ion-exchange column is small for long half lives in comparison to their retention time. Breakthrough may occur some time before column saturation, as indicatsd by the removal of accompanying shorter-lived materials. (N.W.R.)
