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
- 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 UCSD, or no longer possesses radioactive materials.
A recharge, depending on laboratory classification as specified in your RUA, is required to help defray costs associated with maintaining UCSD's 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
