Radiology – Health Physics

The Division of Health Physics manages both the radiation safety and the medical physics imaging program throughout Penn State Health Milton S. Hershey Medical Center.


Please contact us


The Health Physics Division is responsible for conducting both the radiation safety and the medical physics imaging program throughout Penn State Health Milton S. Hershey Medical Center. Our purpose is twofold. First to ensure radiation safety for radiation users, whether they are biomedical researchers experimenting with substances labeled with radioisotopes, medical professionals utilizing radiation for diagnosis or therapy, or patients benefiting from the use of radiation sources to improve their health. Secondly, to provide the Milton S. Hershey Medical Center with a team of medical physics imaging expertise to ensure that all radiographic imaging equipment have the lowest radiation dose and the best clinical image possible.

For consultation, please call the Health Physics office at 717-531-8027.
