摘要：

Comparative measurements of the clay fraction of soils were made with a beta-ray gauge system, a density meter, and a hydrometer. Reliable clay fraction determinations could be made by a beta-ray gauge, and a density meter in less than 25 minutes of sedimentation. The beta-ray gauge measured clay fractions were not affected by surface tension which was the possible cause for variable results obtained with the gamma-ray attenuation technique.
