What Radiation Safety Does

The Radiation Safety Division (RSD) at UCLA EH&S is the operational arm of the Radiation Safety Committee which is a regulatory required body consisting of faculty, clinicians, researchers, and subject matter experts in the field of radiation use. The RSC is authorized by the Chancellor to manage the radiation protection program and oversee the safe use of radioactive materials and radiation-producing machines in clinical, research, and academic settings at UCLA.

Radiation Protection Program
