Office of Radiation Control

Welcome to the Office of Radiation Control (ORC). Our mission is to protect the health and safety of Delawareans by regulating the use of ionizing radiation in medicine, industry, research and education, and to provide health protection resources in the event of a radiological emergency.

This office performs pre-operational inspections for new radiation machine facilities, inspects and registers facilities that use radiation machines, registers facilities that use radioactive materials, registers radiation service providers, and issues certificates for administering radiation to human patients, by qualifying medical and dental radiation technologists and technicians.
