Packaging of radioactive waste must be done as described below. Every effort should be made to minimize radioactive waste volume. Always take extra care to package waste properly to ensure that spills and the spread of contamination are prevented.
Waste Pickup Request
You can request a waste pickup by completing the online request form. Waste bags and yellow radioactive waste bags can be requested when completing the form.
Radioactive Waste (RAM waste) Segregation Criteria
Separate waste by Radionuclide (if experimentally possible)
- Short-lived RAM (t½ ≤120 days) separated from long-lived RAM (t½ >120 days).
- H-3 and C-14 animal carcasses and scintillation vial waste separated from all other radionuclides.
- Deregulated Waste: animal carcass or scintillation cocktail with activity <50nCi/g or nCi/ml.
- Regulated Waste: animal carcass or scintillation cocktail >50nCi/g or nCi/ml.
- Uranium and thorium separated from each other and from other RAM.
Separate waste by Physical Form
- Dry waste separated from all other waste forms.
- Scintillation vials and bulk cocktail separate from each other and all other waste forms.
- Animal bodies separate from biological waste and dry waste.
- Aqueous (inorganic) liquids separate from mixed (organic) liquids (if experimentally possible) per online Radioactive Liquid Waste Segregation list.
- Metals separate from all other RAM waste.
- Uranium and thorium separated by differing compounds (natural, nitrate, or acetate).
RAM Waste Packaging Acceptance Guidelines
- Glass containers, thin-walled plastic containers (milk jugs, soda pop bottles and bleach bottles), leaking containers and unpackaged yellow poly bags containing any glass, loose scintillation vials, liquids and/or exposed sharp objects will not be accepted.
- Waste containers may not weigh more than 50 lbs.
- Plastic containers must be chemically compatible with liquid waste chemistry and pH to prevent leakage or loss of integrity.
- Do not process liquid waste as dry waste by use of absorbents.
- Each container must be tightly secured so that the contents cannot be dispersed (using fiber reinforced or duct tape, tightened screw caps, properly sealed lids, etc.) before pickup. (Various radioactive material ‘caution’ or masking tapes are not acceptable for securing packages.)
- Each container must be labeled with two (2) Waste Classification Labels (labels should be placed 180o apart or on opposite sides of the container) during collection and a Radioactive Waste Summary prior to requesting a waste pickup.
- The Radioactive Waste Summary must include all Radioactive Material Receipts (RMR’s) contained in the RAM waste container. Instructions for completing the Radioactive Waste Summary are on the RLSS website.
- ALL PATHOGENIC or INFECTIOUS MATERIALS must be deactivated prior to pick up (collection by the RLSS), in accordance with the specific authorized protocol.
- Solid waste contaminated with 35S, 125I or 131I may be difficult to safely deactivate due to radioactive vapor generation, resulting in airborne hazards and/or inadvertent equipment contamination.
- ANY QUESTIONS REGARDING DEACTIVATING INFECTIOUS MATERIALS SHOULD BE DIRECTED TO RESEARCH LABORATORY & SAFETY SERVICES AT (520) 626-6850.
Sharps and Glass
- Thick-walled plastic containers with screw tops
- Sharps containers
- Heavy cardboard boxes lined with yellow poly bag. Exterior surface of the box must be labeled “Sharps” boldly written on two sides in clear view
Non-Sharps Dry Waste
- Yellow poly bags
- Heavy cardboard boxes with a poly bag liner
This includes inorganic (aqueous) liquids, organic (mixed) liquids, and bulk scintillation cocktails.
- Sealed plastic pails with pull rings intact. Leave at least 2” free space (air) at top
- Thick-walled plastic containers with tight-fitting screw tops
- Cubitainers (plastic bladder in heavy cardboard box)
- Scintillation cocktail may NOT contain pathogenic materials
For bulk scintillation cocktail, please see Liquid Waste guidelines.
Stored Upright in Tray
- Multiple trays in a heavy cardboard box lined with a yellow poly bag
- Yellow poly bag (single trays only)
Stored Out of Tray (Loose)
- Plastic pails
- Yellow poly bag lined box if >25 lbs
This includes entire carcasses as well as tissues and organs.
- Yellow poly bags (double-bagged) if <25 lbs.
- Yellow poly bags (double-bagged) placed into a heavy cardboard box if >25 lbs
This includes excreta, body fluids, and tissue and cell cultures.
- Yellow poly bags (double-bagged) if <25 lbs.
- Thick-walled plastic container with tight fitting screw top.
- Sealed plastic pails with pull ring intact.
- Heavy cardboard boxes lined with yellow plastic bag if >25 lbs.
