RAD WASTE CONTAINERS

2.5 gal carboy(10 L)

(CRS 721925)

30 gal. Fiber drum

(CRS 768900)

5 gal plasticbucket

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

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)

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 waste by ISOTOPE

Short lived mixed waste by 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 wastes

Must 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 WASTEDetermine 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.
