PREPARATIVE-SCALE SIZE FRACTIONATION OF SOILS AND SEDIMENTS AND AN APPLICATION TO STUDIES OF PLUTONIUM GEOCHEMISTRY

Abstract

A modified elutriation procedure is described for the physical separation of soils and sediments based on particle size. The size distribution of fractions obtained by this method is directly verified and indicates that acceptable separation of silts and clays may be obtained. Studies of plutonium distribution with particle size indicate that the greatest concentrations are in the smaller size classes, which are most subject to erosional transport.
