Radioactive Waste Guidelines
Radioactive Waste Segregation
- Segregate radioisotopes by waste type:
- Solid Waste - lab debris (paper, etc.), disposable gloves, plastic pigs
- Non-hazardous Liquid Waste - buffers, aqueous liquids with a pH between 7 and 11
- Hazardous Liquid Waste - flammable, corrosive, toxic, etc.
- Liquid Scintillation Cocktail - vials containing scintillation cocktail
- Sharps - needles, razor blades
- Bio-hazardous Waste - animal carcasses or tissue
- Lead - pigs, bricks, foil
NOTE: Recycle your lead containers and lead foil for FREE! DO NOT place your lead containers and lead foil into your dry radioactive waste containers. Simply call EH&S at 824-6200 to have your lead containers and lead foil picked up at no charge to you.
- Within each waste type, segregate radioisotopes by half-life:
- < 15 days (such as 32P and 111In)
- 15 - 28 days (such as 33P and 51Cr)
- 29 - 60 days (such as 59Fe and 125I)
- 61 - 90 days (such as 35S)
- 90 days (such as 3H, 14C, 57Co, 22Na, 45Ca)
Radioactive Waste Labeling And Storage
- Use labels and containers provided by EHS for labeling and storage of radioactive waste. Call EHS at 824-4862 to request empty containers and labels.
- Always place liquid container in secondary containment to adequately contain all of the contents of the container/spilled materials.
- Mark storage areas with " Caution Radioactive Material" signs that include the magenta trefoil radiation symbol.
- Keep containers closed when not in use.
- Do not dump it down the drain!
- Do not dispose of radioactive materials/waste via sinks or trashcans.
- Do not intentionally evaporate radioactive materials/waste.
