It is not necessary to perform the personnel contamination survey in exactly the order listedbelow, but a consistent procedure should be followed to help prevent accidentally skippingan area of the body. Pause the probe for about five seconds at locations most likely to becontaminated.1. Top and sides of head, face (pause at mouth and nose for approximately five seconds;high readings may indicate internal contamination).2.Front of the neck and shoulders.3.Down one arm (pausing at elbow), turn arm over.4.Backside of hands, turn over (pause at palms for about five seconds).
515.Up the other arm (pausing at elbow), turn arm over.6.Shoe tops and inside ankle area.7.Shoe bottoms (pause at sole and heel).As with the screening survey, return the probe to its holder on the meter when finished.Donot set the probe down on the ground.The probe should be placed in the holder with thesensitive side of the probe facing to the side or facing down so that the next person to use themeter can monitor his/her hands without handling the probe or allowing contamination to fallonto the probe surface.The most common mistakes made during the survey:Holding the probe too far away from the surface (should be about 1-2 inches away for ascreening survey or about 1/2 inch or less for a detailed survey).Moving the probe too fast (should be about 2-4 inches per second for a screening survey orabout 1-2 inches per second for a detailed survey.)Contaminating the probe.Probe background should be observed and compared to initialbackground.If within a factor of 2, it is acceptable to continue to use probe.Otherwise,check with radiation control personnel. Wrapping the probe in plastic wrap will help preventsurface contamination.

53HOW TO PERFORM DECONTAMINATION AT HOMEYou may have been exposed to low levels of radioactive particles.The particles may havesettled on your hair, skin and clothing as dust.You are not in immediate danger from these smallradioactive particles, however you do need to go home or to another designated area todecontaminate.Removal of outer clothing should reduce your contamination by up to 90%.Inorder to help protect your health and safety as well as others, please follow these directions.
