All
equipment in which radioactive materials have been used or stored
must be surveyed and decontaminated (if necessary) before being
surplused, repaired, or moved by transportation personnel.
Any detectable
contamination in an accessible area of the equipment must
be adequately decontaminated. If detectable contamination
remains after a reasonable decontamination effort, contact
the Area Health Physicist.
All "Caution
Radioactive Material" labels or tape must removed or
defaced after successful decontamination.
The lab
staff must complete a Form NIH 2683 (Certification that Equipment
is Free from Hazards) which can be purchased from the self-service
store, for each piece of equipment being repaired or surplused,
regardless of whether or not the item was used with radioactive
materials. If the items was used with radioactive material,
the lab is responsible for taking smears of the unit, defacing
all radiation labels and maintain the survey record for 3
years. Official DRS clearance is typically not required for
lab equipment, except for liquid scintillation
and gamma counters.
