X-Ray Facility Registrations, Surveys, and Inspections

The x-ray unit has an online payment system available.

Please be aware that during our peak registration renewal process, from November 1 to January 7, processing of online registration forms, as well as responding to emails and voicemails, will take significantly longer due to volume. We ask for your patience and understanding during this busy season.

Alternatively, a check made payable to Department of Health Services (DHS) to can be submitted to the following :

DHS X-ray Protection
PO Box 93521
Milwaukee, WI 53293-3521

The check must have a copy of the x-ray facility's Initial Registration Requirements and Initial Registration Invoice or X-ray Facility Registration Renewal Invoice. (A payment made by check without the accompanying documentation will be significantly delayed.)

Please do not use "Bill Pay" as an alternative to using our online payment system or submitting a paper check.

If you have questions, please email the Radiation Protection Section, or call 608-267-4782.

There is no log-in requirement to access the form. If you are seeing a log-in screen, or if the form does not appear, please use a different browser (ex. Internet Explorer) to submit your information. We are currently working to resolve this issue.

Please note that a change in ownership of an existing facility requires a new registration fee and then a new registration number will be generated.

Notifications of changes or additions to the x-ray devices of existing registered facilities must be provided within 30 days. To register changes in the number of tubes (new x-ray devices or a change in the tube count), please use the online DHS X-ray Initial Registration/Change form, using the drop down list for "Add X-ray device," "Remove X-ray Device," or "Update X-ray Device."

Please note:

  1. Multiple x-ray units at a single radiation installation and under the control of one person may be registered on a single registration application and for one fee.
  2. If the units/sources are located at separate addresses, each installation will require a separate registration and fee.
  3. Registration of sources of ionizing radiation must be made by the person in control.
  4. Renewal Renewal Invoices are sent out by the Department of Health Services in November of each year.
