If you have no near-term plans to use radioactive materials, you can eliminate unnecessary work by deactivating your radiation permit.
This means that you are no longer required to perform monthly surveys in the lab, and DRS personnel will no longer perform radiation surveys and audits of your lab.
If you wish to resume work with radioactive materials, order them as you have in the past. DRS personnel will reactivate your permit, and when they deliver the radioactive materials to your lab, they will re-post the “Radioactive Materials” signs on the lab doors.
Depending on the length of deactivation (> 1 year), DRS personnel may request a lab visit to review any new changes in procedures.
