How Do I Collect Radioactive Waste Safely?
Waste containers are provided by EHSO for use in the laboratory:
- 20 gallon stapacks for dry waste,
- 5 gallon plastic buckets for liquid scintillation vials or dry waste, and
- 1 gallon plastic bottles for liquids.
- Alternate containers for radioactive waste must be approved in advance by EHSO.
Label containers with:
- the isotope(s) to be placed in the container,
- the Radiation Permit Holder’s name, and
- container number (from EHSAssistant) prior to putting the container into use;
Remove or deface any radioactive markings from primary containers before placing material in waste container.
When sealed for transfer to EHSO, add to the label:
- the amount of activity as calculated by EHSAssistant,
- radiation exposure rate (in mR/hr) at surface of the container,
- exposure rate (in mR/hr) at 1 meter from container,
- name of surveyor, and
- date of survey
Lead shielding must be disposed of with EHSO separate from all other waste and must never be placed in a radioactive waste container.
