DEVELOPMENT OF NUCLEAR METHODS FOR MEASURING DENSITY AND NATURAL WATER CONTENT OF SOILS

STUDIES CONDUCTED SINCE 1961 TO INVESTIGATE AND ELIMINATE INTERFERENCE AFFECTING MEASUREMENT OF THE DENSITY AND NATURAL WATER CONTENT OF SOILS BY THE NUCLEAR METHOD ARE REPORTED. STUDIES BASED ON NEUTRON TRANSPORT AND DIFFUSION THEORIES MADE IT POSSIBLE TO OBTAIN A COMPLETE PICTURE OF THE WAY IN WHICH THE MEASUREMENT OF THE NATURAL WATER CONTENT IS INFLUENCED BY CHEMICAL COMPOSITION AND DRY DENSITY OF THE SOIL. THE INFORMATION THUS OBTAINED WAS APPLIED IN BUILDING AN ORIGINAL EPITHERMAL NEUTRON PROBE INCORPORATING A SPECIAL HELIUM-3 COUNTER. A REVIEW IS PRESENTED OF THE FIELDS TO WHICH THE USE OF NEUTRON AND GAMMA RAY PROBES HAVE BEEN EXTENDED, INCLUDING MEASUREMENT OF TOTAL AND PARTIAL POROSITY OF SOILS, AND MEASUREMENT OF SUSPENDED LOAD IN RIVERS, AND OF DENSITY OF MATERIALS NEWLY DEPOSITED IN LAKES. /AUTHOR/
