Current status of crushed rock and whole rock column studies
Measurements on a large number of crushed rock columns of tuff, granite, and argillite are discussed. The isotopes /sup 85/Sr, /sup 137/Cs, /sup 133/Ba, /sup 141/Ce, /sup 152/Eu, /sup 95m/Tc, and /sup 233/U were used. Flow rates were varied from approx. 30 to approx. 30000 m/y. Other parameters studied include isotope concentration and atmosphere. The sorption ratios calculated were compared with batch sorption ratios on the same samples. Methods of studying the movement of radionuclides through whole rock cores are described. The problems associated with sealing the cores to prevent leaking along the exterior surface and one possible solution are discussed. The strontium sorption ratio obtained by elution of one solid tuff core is compared with the batch and crushed rock column sorption ratios.
