Radioactive Waste
at UF
Bldg 831
392-8400
Radioactive Waste
• Program is designed to;
• Minimize cost to researchers
• Minimize time spent by lab
workers
• Insure compliance with rules
Radioactive Waste
• Program requires
• Generator support
• Proper segregation
• Packaging
• labeling
Radioactive Waste
• What is radioactive waste?
• Anything that
• Contains
• or is contaminated
• Not the second rinse.
Handling for disposal
• Based on available options
• Long T1/2 (> 90 day)
• Burial
• Incineration
• Short T1/2 ( < 90 day)
• Hold for decay
Radioactive Waste
• Sorting (segregation)
• Physical form
• Separate liquid from solid
• Radionuclide
• Separate all but H3/C14
Radioactive Waste
• Segregation
• Why?
• Half-life
− P 32 = 14.5 days = decay in storage
− H-3 = 12.3 years = burial
− (substantial cost savings, common in med use
also)
Radioactive Waste
• Packaging
• Liquids
• In containers EHS provides ONLY
unless non-compatible
• Solids
• Clear Bag (health center stores)
• And/or Box (recycled from HC stores)
Radioactive Waste
• Labeling
• Rad Sticker
• Pi, isotope, date filled, activity
• Chem stickers
• Common Compound name, percentage of
total volume
• Legible
Radioactive waste
• Containers when filling
• Labled
• Closed
• No spills ( containerize)
Radioactive Waste
• Vials
• U-fuge tubes
• Must remove liquids
• Scintillation
• Original flat or bag lined box
• Do not remove liquids
Radioactive Waste
• Radio-immunoassay kits
• Some contain mercury
• Identify as “kit waste”
• Segregate liquids
Radioactive Waste
• Liquid Scintillation fluid
• When possible use cocktails such as
• Scinti-safe
• Bio-safe
• Ready safe
• Non solvent based
• See literature for sample loading, solubility
Radioactive Waste
• Animals
• Deceased
• Double bagged
• frozen
Radioactive Waste
• Dry Waste
• Absolutely no liquids
• No liquids in vials
• Segregate H3/C14 by type
• Pack non sharps in clear bag or
bag lined box
• Pack sharps in lined box
• lable
Radioactive Waste
• H3/C14 solids
• Type A ( incinerable)
• Paper
• Plastic
• Poly
• Wood
• Cotton
• latex
Radioactive Waste
H3/C14 solids
Type B (non-incinerable)
metal
glass
hazardous materials
Radioactive Waste
• Biohazardous Radioactive
Waste
• Biohazard must be deactivated
• Avoid bleach if possible
• See EHS biosafety manual for
alternatives
• NO RED BAGS
Mixed Waste
• EPA – mixed is hazardous waste
and radioactive waste mixed
together
Mixed Waste
• Chemical Waste?
• Listed
• Characteristic
Mixed Waste
• Characteristic chemical waste
•
•
•
•
Flammable
Corrosive
Reactive

Mixed Waste
• Listed waste
• U list
• P list
• F list
Mixed Waste
• Very important to;
•
•
•
•
•
•
Label container
Do not add MW to non MW
Very expensive to dispose of
1% = 10,000 ppm
CHCl3 is HW at 6 ppm
Hg is HW at .2 ppm
Mixed Waste
• Must also have the words
“hazardous waste” on the
container.
Radioactive Waste
• Good practices
• Don’t generate more than you have
to.
• Don’t generate mixed waste
• Don’t mix isotopes
• Contaminated material only in MW
