Unescorted access to irradiator facilities at the University of Toronto requires staff, students and faculty to undergo the Trustworthiness Verification process and complete the necessary safety training. In order to become authorized for unescorted access all applicants must:
- Step 1: Send the Radiation Safety Officer (RSO) an e-mail requesting access with the following information:
- Permit Holder or supervisor authorization
- Updated CV or resume with at least five (5) year history
- Confirmation of completion of the online training EHS 710: Sealed Source Safety (see the Training Registration page for more guidance)
- Step 2: All applicants must undergo a Criminal Record Name Check (CRNC) and obtain a ‘Negative’ finding in order to receive authorized access. The RSO will send a request on behalf of the applicant to the U of T Campus Safety to commence the CRNC process.
- Note: a fee is charged to the home department for background checks
- Step 3: Campus Safety will inform the RSO of the findings of the applicant’s CRNC. Upon confirmation that CRNC is ‘Negative’ for findings, the RSO will complete with an authorization form with the applicant and their supervisor.
- Step 4: The RSO will contact Campus Safety to issue access to the authorized worker.
- Note: a fee is charged to the home department of the worker and they must have a valid FOB
- Step 5: Once access has been granted, onsite training on the irradiator will be provided by the RSO
- Step 6: The applicant becomes an authorized irradiator user and is attached to the irradiator permit of the supervisor/permit holder.
