Radiation (X-ray) Machine Registration

Effective June 26, 2024, RHB will no longer issue Certificates of Registration upon initial registration or renewal.

Registration verification is now available through our online registration verification page.

What is X-ray Machine Registration?

Title 17, California Code of Regulations § 30108 requires that when an entity acquires a radiation machine, they must register with the Radiologic Health Branch (RHB) within 30 days.

The registration process is completed through the Radiation Machine Registration Portal.

Facilities will be given a facility registration number (FAC 000XXXXX). Radiation machines can then be added or removed from the facility inventory.
