Use of Californium-252 in Laboratory Testing for Moisture and Density of Soils.

This report is primarily concerned with illustrating methodology for the identification and quantification of moisture along thin, discrete layers of opened and unopened soil cores. A major portion of the work has been devoted to scanning of soils encased in a 2.875-in.-inside-diameter ID steel sampling tube. Some neutron film imagery, however, was also obtained to illustrate the distribution of moisture that can and does occur within individual soil samples.
