Description/Abstract:
DECONTAMINATION IS THE PROCESS OF REMOVING FALLOUT MATERIAL FROM SURFA CES TO REDUCE THE RADIATION DOSE THAT WOULD BE RECEIVED BY ANYONE EXPO SED TO THE FALLOUT. THE REMOVAL OF SUCH FALLOUT IS VERY SIMILAR TO CL EANING BY ORDINARY METHODS. THESE METHODS INCLUDE HANDBROOM SWEEPING, MECHANICAL STREET SWEEPING, MECHANIZED VACUUM CLEANING, AND FIREHOSIN G. PHYSICAL MODELS OF CLEANING PROCESSES ARE DESCRIBED AND MATHEMATIC AL FORMULATIONS ARE DEVELOPED THAT RELATE THE FALLOUT-MASS REMOVAL TO TIME SPENT IN THE CLEANING PROCESS FOR THREE CASES: (1) THE LAYER TO BE REMOVED IS THIN AND NO MASS PILES UP IN FRONT OF THE CLEANING EQUI PMENT, (2) THE LAYER IS THICK AND NO PILING UP OCCURS, AND (3) THE LA YER IS THIN OR THICK AND PILING UP OCCURS. RECOMMENDATIONS ARE SUGGES TED FOR THE CONDUCT OF ANY FUTURE DECONTAMINATION EXPERIMENTS TO OBTAI N ESTIMATES OF THE VALUES OF BASIC-EQUATION PARAMETERS.
