Determination of the amount of ion exchange resin in concrete containing radioactive wastes

A method for determining the amount of ion exchange resin in waste concrete was tested on a (approximately 2 g) piece of concrete containing a known amount of ion exchange resin. The difference between the reference and the analysis values was less than ten per cent, and it seems likely that the reproducibility is considerably better. It was concluded that the method is suitable for homogeneity determinations, although some further experiments are needed before it can be used as a standard method. (Auth.)
