The use of liquid scintillation for the assay of C 14 in layer silicate and soil suspensions is evaluated by various procedures with several scintillator media. The effects of sample weight, color, settling time, and the level of activity on the counting characteristics of scintillator media which contain soils and layer silicates are presented. Highly statistically significant linear regressions, which differed for each solid tested, were obtained between the level of activity added and the observed activity. The differences between the materials tested were related predominantly to the color which the solid imparted to the scintillator medium. A procedure for the determination of the retention of carbon compounds by layer silicates and soils is presented. The procedure described is specific, but can easily be modified to fit the needs of related studies.
