X-Ray Inspections

The Department of Health requires registration of all X-ray machines through the Master Business Licensing service of the Department of Revenue.

The X-Ray Program evaluates darkrooms and film processing, machine performance, image quality, technologist qualifications, operator protection, and - most importantly - patient exposure.

There are more than 6,500 facilities using X-ray machines in Washington.

More information about state regulations is on the WAC - X-Ray page.
