Radioisotope Use Authorization: Overview
Learn about eligibility requirements, recharge rates, and when to amend, renew, and deactivate the Radioisotope Use Authorization (RUA).
Requirement
Principal investigators (PI) must obtain a Radioisotope Use Authorization (RUA) to possess and use radioactive materials for research.
The RUA is an agreement between a PI and UC San Diego specifying how and where radioactive materials will be used. Keep a copy of the RUA available for inspectors in the main radioactive materials use area.
To be eligible for an RUA, the PI must:
- Be a faculty member
- Have an independent space assignment
- Have independent funding
- Attend the Radiation: Safety Seminar or equivalent
Apply for and manage a RUA
- See Apply for and Manage a RUA for application procedures.
Amend the RUA when any of the following critical elements change:
- Project summary
- Isotopes
- Lab manager or personnel
- Work locations
- Human or animal protocols
Renew the RUA 1 year after initial approval, and annually every year thereafter. Environment, Health & Safety (EH&S) will notify the PI when it's time for renewal.
Deactivate the RUA when the PI is retiring, leaving UC San Diego, or no longer possesses radioactive materials.
Recharge rates
A recharge, depending on laboratory classification as specified in your RUA, is required to help defray costs associated with maintaining the UC San Diego State of California radioactive materials use license. The following rates apply:
- Low-use lab – $65 monthly
- High-use lab – $195 monthly
- Sealed source lab – $65 monthly
- Sealed source labs authorized to posses 1 and only 1 generally licensed device may be exempted from the monthly recharge at the discretion of the Radiation Safety Officer
