Whether your organization's focus is improving the environment or protecting worker health, ORAU can develop solutions to meet your health physics and radiation safety needs.

Health physicists understand that radiation can be beneficial to industries such as healthcare, manufacturing, agriculture and the environment. Even everyday items in our homes—such as smoke detectors and granite countertops—contain small amounts of radioactive isotopes that are generally safe when used as intended. However, industrial uses of radiation must be managed and controlled to protect workers, the public and the environment from hazardous exposure levels. 

ORAU's history and health physics expertise reaches back to the post-Manhattan Project nuclear era and some of our early work focused on the use of isotopes in medicine. From establishing a cancer research hospital and medical division that became a nationwide resource for physicians seeking knowledge in the growing field of nuclear medicine, ORAU's expertise in health physics and radiation safety spans much of our history.

Though our mission today has changed, ORAU has never wavered in its focus on providing the expertise to help our government and private-industry customers monitor and evaluate radiation exposures to workers and the environment. We also provide health physics training through our Professional Training Programs (PTP) to help your employees stay up-to-date on the latest techniques in radiation safety and environmental monitoring.

What is health physics?

Health Physics is the profession of radiation safety. Practitioners, known as health physicists, are scientists that share the common goal of protecting people from the harmful effects of ionizing radiation while maximizing the benefits to mankind from the uses of radiation and radioactive materials.

Health physics at ORAU

Having been involved in the health physics profession since it began, ORAU has developed into a key member of the larger health physics community. ORAU currently employs more than two dozen health physicists across multiple business units. These include:
