Pathological Radioactive Waste Packaging & Disposal

Pathological radioactive wastes include: contaminated animal carcasses, organs, blood, tissue, urine, feces, bedding, etc.

  • Pathological wastes must be completely frozen to be accepted by OSEH personnel.
  • Remove all sharps (e.g. needles, razors, scalpels, etc.) and metallic objects from carcasses before freezing and subsequent OSEH collection.
  • Radioactive blood, tissue, urine, etc. must be made innocuous or rendered non-toxic prior to OSEH collection (e.g. bleach, detergent, other methods). WARNING: Radioiodines or other volatile radionuclides may become airborne when bleach is added.
  • Double-bag animal carcasses in strong (4 mil) plastic bags.
  • Outer bag or wrapper should be a yellow opaque bag available from OSEH.
  • Contact OSEH for authorization to use the walk-in freezer located in MSRB-II (Rm A592). Key-use required for entry.
  • OSEH must be notified in writing should an Authorized User desire to store radioactive pathological material in an animal freezer under the authorization of another individual or department.
  • Contact OSEH if a radioactive storage freezer is filled to capacity, breaks down, or otherwise becomes ineffective in completely freezing animal carcasses, blood, etc.
  • Attach OSEH provided yellow waste tag with the following instruction: radionuclide(s), activity of each radionuclide (┬ÁCi), chemical or biohazardous material (if applicable), date packaged, description of waste (e.g. rats, dog, mice, pig, bedding, blood, feces, etc.), names of contact person and Authorized User, and phone number(s).
  • Do not dispose of plastic cages as pathological waste. (Note: empty contents of animal cages into pathological waste bags or 4 mil thick plastic bags and decontaminate cages).
  • Do not discard pathological wastes into yellow waste drum.
  • Do not freeze pathological wastes in glass containers. (Note: use plastic only).
  • Do not discard metal objects (e.g. needles, scalpels, cans, etc.) with pathological material or animal carcasses.
  • Do not discard (≥ 5.0 mCi of I-125 and/or I-131 in a single bag or container of pathological waste.
