It must be collected and disposed of separately as a radioactive waste. Each container must be labeled with the amount of uranyl acetate, in grams, specified. DO NOT MIX uranyl acetate solutions with other nonradioactive waste, such as lead citrate. To dispose of liquid scintillation vials, ensure the vials are tightly-capped to minimize leakage, and place them into a container that is lined with two yellow plastic bags or return them to their shipping trays, if available, and place those into yellow plastic bags. Fill each bag no more than about half full.
Overfilled bags become too heavy and are difficult to manage.
Scintillation Cocktail - Liquid scintillation vials are not to be emptied unless the investigator wishes to reuse them. In this case, the used scintillation cocktail must be poured from the vials into a clearly labeled waste container for bulk radioactive liquid. You must clearly indicate on the container that it contains scintillation cocktail. Do not place liquid scintillation vials into solid dry waste containers unless the vials have been emptied and thoroughly rinsed. This includes vials containing non-ketone based liquids.
