Although these liquid scintillation fluids are considered to be "biodegradable" and "environmentally safe", please remember that they still present a disposal concern. Scintillation fluid wastes should only be disposed of through OSEH Hazardous Material Management (HMM). Call HMM at 763-4568 to request a waste collection or if questions arise.

Note that manufacturers may make a family of scintillation cocktails with very similar names, but very different properties, making one an approved cocktail and its cousin an unapproved cocktail. Be very careful when ordering and using scintillation cocktails. Ensure that the proper scintillation cocktail is recorded on your LLRW Waste manifest also.

If you using, or plan to use, a scintillation cocktail that is not on the approved list please contact RSS (764-6200) or HMM (763-4568) immediately. Temporary authorization may be granted to use a non approved scintillation cocktail. Additional handling and processing steps are required of the laboratory to ensure proper disposal of non approved scintillation cocktails.
