Gary, 

You did not mention, what radionuclides you want to concentrate and
measure. There is the possibility of adsorbing any ion on the right
exchanger. I would recommend to rather search in the literature for the
radionuclides and find in connection with "ion exchange" the method to
solve your problem.

There are other possibilities for concentrating radionuclides - crown
ethers (EIChrom), adsorption materials etc.
