Cages & Pens

Authorized users and Unit for Laboratory Animal Medicine (ULAM) personnel are responsible for decontaminating animal cages and pens where animals are housed that have been used for research with radioisotopes.

  • Maintaining documentation of all swipe survey results for cages/pens.  NOTE: Survey records are subject to RSS and NRC inspections.
  • Notifying the ULAM area supervisor of the swipe survey results after the cages/pens are found to be free of radioactive contamination.
  • Following successful decontamination, removing:
    • Animal color-coded cage cards.
    • Other postings on the cages and pens, and room doors.
  • Returning animal color-coded cage cards to the ULAM area supervisor.
