The University of Toronto Radiation Safety Program oversees the safe use and possession of radioactive materials across all three U of T campuses according to the regulations set by the Canadian Nuclear Safety Commission (CNSC) under the authority of the Nuclear Safety and Control Act (NSCA). The program is implemented and enforced by the Institutional Radiation Protection Committee (IRPC) through the EHS Radiation Protection Service (RPS) team.

Radioactive Materials
Radioisotope Inventory Management
Authorized radioactive materials permit holders and their authorized users can access their radioisotope inventory through the Radioactive Materials module in SPROUT. Log into SPROUT to access the following features:
- Tracking and receipt of radioisotope orders
- Radioisotope inventory management
- Contamination monitoring records
- Radioactive waste disposal requests
Radioactive Materials and Devices Permits
An EHS Radioactive Materials (RAM) permit is required for purchasing, possessing and using radioactive materials at the University of Toronto. General information related to applying for a permit can be found below. Please contact the EHS Radiation Protection Service for any inquiries or assistance related radioactive materials permits. To view, amend or apply for a new RAM permit please log into SPROUT.
