摘要：
The content of silver fission product and its radial distribution in spherical coated fuel particles can be measured by stepwise chemical removal of pyrolytic carbon layers coupled with an anion-exchange separation procedure and subsequent γ-counting. An adsorption efficiency better than 98% ranging over five orders of magnitude in silver concentration was found for a bromide-containing medium. Silver to carbon ratios down to 10-12 are measurable so that this method is useful for studying the diffusion of silver in pyrolytic carbon. © 1979.
