SCINTILLATION METHODS FOR THE DETERMINATION OF DENSITY AND MOISTURE CONTENT OF SOILS AND SIMILAR GRANULAR SYSTEMS

NUCLEAR METHODS FOR MOISTURE AND DENSITY DETERMINATIONS IN SOILS HAVE REACHED A POINT OF DEVELOPMENT THAT MADES THEM VALUABLE TOOLS TO THE ENGINEER AND SCIENTIST. THE PAPER FIRST TRACES THE HISTORY OF THE AVAILABLE TECHNIQUES AND DISCUSSES THE UNDERLYING SCIENTIFIC PRINCIPLES AS WELL AS THE CARACTERISTICS OF THE VARIOUS AVAILABLE PROBES AND OF THEIR COMPONENTS. SUBSEQUENTLY, THE PRINCIPLES AND AVAILABLE METHODS OF SCINTILLATION DETECTION ARE DESCRIBED AND ARE APPLIED TO THE DESIGN OF ACTUAL MOISTURE AND DENSITY PROBES. THE PERFORMANCE OF THESE PROBES IN LABORATORY AND EXTENSIVE FIELD TESTS ARE GIVEN AND THEIR ADVANTAGES AND SHORTCOMINGS POINTED OUT. EMPHASIS IS PLACED ON MEETING THE PRACTICAL PROBLEMS ENCOUNTERED IN FIELD CONDITIONS AS THEY AFFECT THE OPERATION OF THE PROBES AND ASSOCIATED ELECTRONIC EQUIPMENT, THE PREPARATION OF HOLES THROUGH VARIOUS SOIL TYPES, THE READINGS OBTAINED BY THE INSTRUMENTS USED, AND THE CALCULATION OF RESULTS, SO AS TO GIVE THE MOST ACCURATE DETERMINATIONS OF SOIL MOISTURE AND DENSITY. /AUTHOR/
