RADIATION/CONTAMINATION SURVEY
PRINCIPAL INVESTIGATOR: Dr. Who
When to
document a
survey?
A survey must be documented
within seven days of isotope
use
(Best to schedule one day a
week)
OR
If the lab has isotope storage
only (no use) or waste still on
hand…a documented survey
once a month

Minor
Spill
< 100 µCi of activity
< 5 mR/hr at one foot
In the Event of a Minor Spill
 Notify everyone in the area
 Prevent the spread of contamination
 Call for help if needed
 Decontaminate
• Only trained staff may handle spill
• Monitor potentially contaminated staff first
(before leaving the area)
• Lab coat and gloves (shoe covers if necessary)
• Start from the outside and work your way in
• Use absorbent paper and detergent as needed
 Survey
• Below 100 dpm / 100 cm²
Major Spills
• Personal contamination or injury
• >100 µCi of activity
• >5 mR/hour at one foot
In the Event of a Major Spill
 Remove individuals from danger
 Call 911 if serious injury
 Limit the spread of contamination &
shield if possible
 Call Radiation Control
 Close, lock and post the room
 Decontaminate under the direction of
Radiation Control
Personal Decontamination:








Remove contaminated clothing
Use sticky tape
Flush with water
Soap and warm water
Mild abrasives, soft brush and water
Detergents
Mild organic acid (citric)
Wear gloves
