Subject to the requirements of the California Health and Safety Code and Title 17 of the California Code of Regulations, all radiation machines, except for the following, may be used upon installation.
- Prior to performing mammography, a facility must apply for and receive a mammography machine certificate for each machine. For more information, visit our Mammography Facilities page.
- Prior to using radiation therapy machines with energies above 500 kVp, an authorization from the Department must be obtained. For information on how to apply for the authorization, visit our Therapeutic Facilities page.
7. Do I need to notify the RHB of any changes and, if so, what is the approved method of notification?

Lastly, federal regulations require vendors to notify the RHB of every radiation machine they install using the Report of Assembly of a Diagnostic X-ray System (Form FDA 2579). Form FDA 2579 can be submitted via email to email@example.com.
11. My registration renewal billing notice for my dental X-ray machine is wrong. I am a veterinarian. Why is my machine categorized as a "Medium Priority Radiation Machine" instead of a "Dental Priority Radiation Machine?"
Radiation machines are categorized in accordance with the definitions found in title 17, California Code of Regulations, section 30145. A Dental Priority Radiation Machine is defined as a radiation machine used exclusively in dental radiography of human beings. Thus, an X-ray machine used by a veterinarian is not a Dental Priority Radiation Machine. Further, it does not meet the definition of High Priority Radiation Machine, or Special Priority Radiation Machine. Therefore, it is classified as a Medium Priority Radiation Machine.
12. As a veterinarian, I use my dental machine for dental procedures in the same way as human dental offices do. My machine should be categorized as a Dental Priority Radiation Machine. Why do I pay a higher registration fee than dentists?
Registration fees cover the cost of registering and inspecting radiation machine users. The Radiation Control Law specifies the criteria for prioritizing the inspection of machines and how often a machine is inspected. In accordance with that law, radiation machines used by dentists (i.e., Dental Priority Radiation Machines) are screened for defects by mail or other offsite methodology not less frequently than once every 5 years, with physical inspection of 50% of those machines determined to be most in need of inspection, to average at least once every 6 years. Inspections of other users occur more frequently and are only physical inspections: High Priority is inspected every 3 years; Medium Priority is inspected every 4 ¼ years; Special Priority is inspected annually. Thus, machines used in dentistry are inspected differently and less frequently than other users making the registration fee for a Dental Priority Radiation Machine lower.
13. Who can I contact regarding registration payment submission or questions regarding registration fees?
Questions regarding registration fees or renewal payment submission should be emailed to firstname.lastname@example.org.
If your renewal information or X-ray machine inventory is incorrect, please email email@example.com for guidance.
