The purpose of the Oak Ridge Associated Universities (ORAU) Museum of Radiation and Radioactivity is to chronicle the scientific and commercial history of radioactivity and radiation. It has been deemed the official repository for historical radiological instruments by the Health Physics Society, and the Society has been generous in its financial support for the purchase of items.

The collection is the property of the not-for-profit ORAU Foundation, and it is located at the Professional Training Programs (PTP) training facility in Oak Ridge, Tennessee. Unless noted otherwise, this website only features items actually in the collection.
