RAD WASTE CONTAINERS 30 gal. Fiber drum (CRS 768900) 5 gal plastic bucket 2.5 gal carboy (10 L) (CRS 721925) Correctly label and use liners!
IDENTIFY YOUR WASTE STREAMS ! WASTE MINIMIZATION ! DO YOU SURVEY ALL YOUR DRY TRASH BEFORE PUTTING IT INTO THE RAD WASTE DRUM? DO YOU AUTOMATICALLY CONSIDER ALL MATERIALS USED IN THE EXPERIMENT CONTAMINATED? SOME MIXED WASTES GENERATED IN THE LAB CAN BE TREATED IN THE LAB, I.E., NEUTRALIZATION, SOLVENT EXTRACTION, PRECIPITATION, DISTILLATION, ETC. MUST BE WRITTEN INTO THE WORK PLAN AND APPROVED BY THE RSO, HOW MUCH WILL YOU BE PAYING FOR RAD WASTE?

DRY RAD WASTE (DAW) Segregate dry solid radioactive waste according the following categories: Long lived DAW (half life >100 days) Short lived DAW (half life <100 days) Incinerable C-14/H-3 DAW (concentration < 0.05 uCi/g) Sealed radioactive sources
DRY RAD WASTE (DAW) CategoriesAssociated Quantity Known Quantity
EACH DAW CONTAINER MUST HAVE THIS FORM EACH FORM SHALL BE INITIATED WHEN THE FIRST WASTE IS PLACED IN THE CONTAINER COMPLETE WHEN FULL OR WHEN YOU WANT TO DISPOSE FORM MUST BE COMPLETED WHEN WASTE IS RETRIEVED MAKE COPY FOR YOUR RECORDS
LIQUID RAD WASTE Segregate Liquid radioactive waste according the following categories: Long lived waste (half life >100 days) by ISOTOPE Short lived waste (half life <100 days)by ISOTOPE Non-biodegradable liquid scintillation counting fluid containing exclusively H-3 and/or C-14 in concentrations not to exceed 0.05 µCi/gram Long lived mixed wasteby ISOTOPE Short lived mixed wasteby ISOTOPE
Rad Waste Study Every Lab should breakdown and analyze every fraction of generated liquid rad waste as a study.If the liquid waste generated is typical of all experiments then this can be done only once. Evaluate Low level LRW versus High Level LRW This study provides information on how to dispose of LRW. Low Level LRW should be sewer discharged High level LRW should be picked up by RSO
LIQUID RAD WASTE Segregate Liquid Scintillation Fluid from all other liquid wastesMust be biodegradable If wipe test results are all <200 dpmnet (66 cpmnet), then the fluid can be poured down the sink without record If sample test results are all <2 SD of BKG CPM plus BKG CPM, fluid can be poured down the sink without record
LIQUID RAD WASTE Determine which route of disposal If the liquid contains exclusively H-3, C-14, P-32, P-33, and/or S-35 in concentrations likely to be less than the ALARA action levels, the liquid may be evaluated for release. Perform and document an analysis and evaluation for release in accordance with the Evaluation of Liquids for Release Form If the liquid does not meet the criteria described above, perform and document analysis for pick-up by Radiation Safety in accordance with the Liquid Radioactivity Analysis for a Waste Pick-Up Form If your Radioactive Materials Permit (license) authorizes sewer disposal, perform and document analysis in accordance with section 5.5, Sewer Disposal Permits.
RSO RAD WASTE PICK UPS 9:00 AM THURDAYS CALL 542-5801 ADD YOUR NAME/WASTES TO THE PICK UP LIST PLACE WASTE ON DOCK THURSDAY MORNING ONLY ALL WASTES MUST BE ESCORTED UNTIL THEY ARE RETRIEVED
