Safe use of ionizing radiation requires the cooperation of many individuals and committees. Their responsibilities are described below.

Principle investigators

Each Principal Investigator (PI) or project director is responsible for ensuring individuals are trained to do their tasks safely, supervising them, making the lab available for inspection at any work time, and ensuring that the project is managed in accordance with the application, the administrative and technical requirements in this manual, and the Hazards Evaluation.

The PI bears the additional responsibility of setting an example for the project staff. Appropriate attention to details, such as strict adherence to standard work rules, accurate survey records, and timely return of dosimeters (e.g., film badges) can affect the work environment and the attitude of individuals.

Individual Users

Each individual user is responsible for following the procedures in this manual and instructions from supervisors and Health Physics, and reporting possible safety problems and incidents.

Administrative Panel on Radiological Safety

The Administrative Panel on Radiological Safety (APRS) oversees the entire institutional radiation safety program for both Stanford and VAPAHCS. It also reviews applications that are outside the jurisdiction of the local control committees.

Local Control Committees

Each Local Control Committee (LCC) is responsible for reviewing applications in its jurisdiction to provide assurance that the work can be done safely and in accordance with the requirements in this manual and the Hazards Evaluation. There are two local control committees: Non‐Human Use Radiation Safety Committee (NHRSC) and Clinical Radiation Safety Committee (CRSCo) for human use applications. The Radioactive Drug Research Committee (RDRC) is a subset of CRSCo. These committees also oversee VAPAHCS projects.

Health Physics

Health Physics, a division of the Stanford University Department of Environmental Health and Safety (EH&S), is the institutional radiation safety program. It also provides radiation consultation. The Radiation Safety Officer, who is identified on the radioactive materials license, is the manager of Health Physics.
