The X-ray machine staff of the North Dakota Radiation Control Program conduct activities associated with machine produced ionizing radiation. A major responsibility is the registration and inspection of X-ray machine facilities, equipment, operators and radiation service providers. All machine sources of ionizing radiation must be registered with the Department. There are over 700 facilities with approximately 1500 X-ray tubes throughout North Dakota. X-ray machines are utilized in a wide range of activities including industrial (airport baggage surveillance, potato packaging, weld verification), research (spectroscopy, diffraction, fluorescence) and healing arts applications for both human and animal patients.

The North Dakota Radiological Health Rules (NDRHR) contain requirements for All X-ray equipment operated in North Dakota. Inspection compliance is based on these requirements. Inspections are prioritized according to potential impact on public and operator health and safety. Inspection frequency ranges from yearly (mammography facilities) to once every seven years (veterinarian). The lead Federal agency involved with X-ray machines is the US Food and Drug Administration (FDA) as authorized by the Federal Food, Drug and Cosmetic Act of 1973. The FDA provides training, equipment and technical expertise to all State radiation control programs.

Copies of the NDRHR are available from the Department or downloadable from our rules page.

IN THE NEWS:  Patient Radiation Doses - Nationwide Evaluation of Xray Trends (NEXT)

What is NEXT?
The Nationwide Evaluation of X-ray Trends (NEXT) program is a partnership between the Conference of Radiation Control Program Directors, Inc. (CRCPD) and the Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH), with financial support from the American College of Radiology (ACR) since 1998, to characterize the radiation doses patients receive during diagnostic x-ray examinations. 

Each year the NEXT survey program selects a particular radiological examination for study and captures radiation exposure data from a nationally representative sample of U.S. clinical facilities.  Volunteer state radiation control personnel conduct the surveys using reference phantoms most of which are clinically validated to represent the radiation attenuation presented by an average-size patient.  Surveys are repeated periodically to track trends as technology and clinical practices change.
