Description/Abstract:
A SOD-CUTTING MACHINE WAS EVALUATED FOR ITS USEFULNESS IN THE RADIOLOG ICAL RECLAMATION OF SMALL LAWN AREAS - SOME OF WHICH WERE CONFINED BY SIDEWALKS, TREES AND BUILDINGS. FALLOUT CONDITIONS WERE SIMULATED BY CONTAMINATING LAWN TEST AREAS WITH RADIO-TRACED SAND. NOMINAL PARTICL E SIZE RANGES OF 44-88 MICRONS, 88-177 MICRONS, 177-350 MICRONS AND 35 0-700 MICRONS WERE USED. THIS FALLOUT SIMULANT WAS DISPERSED AT NOMIN AL CONCENTRATIONS OF 25, 50 AND 100 G/FT SQUARED, RESPECTIVELY. RECLA MATION EFFECTIVENESS OF SOD CUTTING WAS DEPENDENT UPON MACHINE FACTORS (BLADE DEPTH), SOIL CHARACTERISTICS ( MOISTURE CONTENT) AND FALLOUT S IMULANT PROPERTIES (MASS LOADING). THE LEAST EFFECTIVE SOD REMOVAL RE SULTS WERE OBTAINED IN CONFINED LAWNS WITH HIGH MOISTURE CONTENT AND H EAVY ROCK CONCENTRATIONS. THE BEST SOD CUTTING AND REMOVAL EFFECTIVEN ESS RESULTS WERE OBTAINED ON MORE ACCESSIBLE LAWNS HAVING LESS MOISTUR E CONTENT AND ONLY A LIGHT CONCENTRATION OF ROCKS. SIMULANT PARTICLE SIZE WAS FOUND TO HAVE LITTLE, IF ANY, EFFECT UPON RECLAMATION PERFORM ANCE EITHER WITH RESPECT TO EFFORT REQUIRED OR REMOVAL EFFECTIVENESS A CHIEVED.
