BIOLOGICALS
All Radioactive Biologicals including items such as bodies, excrement, organs, contaminated bedding, and tissue samples containing radioactivity should be segregated according to the following isotopic half-lives:
Class 1: Isotopes with a half-life of less than 15 days. (32P)
Class 2: Isotopes with a half-life of 15 to 100 days. (33P, 51CR, 35S, 125I, 111In)
Class 3: Isotopes with a half-life greater than 100 days. (3H, 14C)
Note: Biologicals do not include items such as paper, needles, blood soiled lab coats, etc. For further guidance, please contact the Radiation Waste Department.
PACKAGING REQUIREMENTS
Each class of Radioactive Biological Waste must be placed into separate, properly labeled and sealed clear plastic bags. If the waste is frozen, keep it frozen and the Waste Management Department will pick it up in that condition. Please contact the Radiation Waste Department if your waste is difficult to package or seal and we will assist you with packaging.
LABELING REQUIREMENTS
Each sealed bag must be individually labeled with the following information: Program Number, User Name, Isotope, and Activity. If there are multiple bags inside a storage container or box, please use a drum log to track each sealed bag following the same procedure that is used for Radioactive Dry Waste.
