Description/Abstract:
ZINC SULFIDE POWDER WITH A MEDIAN DIAMETER OF ABOUT TWO mu WAS USED TO DETERMINE THE PROBABILITY OF A SINGLE RADIOACTIVE PARTICLE BEING TRANSFERRED TO THE AIR AND BREATHED IN SEVERAL OPERATIONS INVOLVING OPERATION AND MAINTENANCE OF SEDANS AND BUSSES. A KNOWN NUMBER OF PARTICLES WERE DEPOSITED WITH SOIL NORMALLY PRESENT, THEN THE OPERATION GIVING RISE TO A POTENTIAL EXPOSURE PERFORMED. THE NUMBER OF ZNS PARTICLES FOUND ON RESPIRATORS WORN OR COLLECTED ON FILTERS USED TO SAMPLE THEAIR DURING THE OPERATION WAS DETERMINED USING A MICROSCOPE AND ULTRAVIOLET ILLUMINATION. THE PROBABILITY OF BREATHING A SINGLE PARTICLE WHEN PRESENT WAS FOUND TO RANGE FROM 6 X 10 TO THE -7 PER HOUR FOR DRIVING WITH MINIMUM AIR TURBULENCE IN THE VEHICLE, TO 6X 10 TO THE -4 PER HOUR FOR SWEEPING THE DIRT FROM A BUS. OTHER OPERATIONS AND PROBABILITIES ARE DISCUSSED.
