A sampler for concentrating radionuclides from natural waters

A sampler which permits concentration of both particulate and dissolved radionuclides from large volumes of ocean and freshwater has been developed and tested. The water sample passes through a filtration section for particle removal, then through a sorption section where the radionuclides of interest are removed on sorption or ion exchange beds. Components of the sampler which contact the water are of polyvinyl chloride construction, and flow rates of about 40 l./min are employed. This sampler has been successfully employed in concentrating some twenty radionuclides from ocean and fresh waters.
