X-Ray Machine Registration and Inspection Requirements in Washington State

Washington State law requires that all x-ray machines—including dental units—must be registered before use. Registration happens through the Master Business Licensing Service under the Department of Revenue. That means your practice must register each x-ray unit and pay the associated fees before operating it. When installing a new facility or relocating equipment, a detailed shielding plan must be submitted in compliance with WAC 246-225, to ensure safe operation and protect patient and staff exposure.

Inspections are also mandatory. The Washington State Department of Health schedules inspections based on facility type. Dental offices, along with veterinary, podiatry, and industrial x-ray sites, fall under a 3- to 4-year inspection cycle. Inspectors evaluate several technical and safety elements, including the quality of image production, darkroom or processing performance, operator protection measures, and overall radiation safety, aligned with the ALARA ("as low as reasonably achievable") principle. These evaluations help ensure that clinics providing care to treat receding gums Marysville patients maintain the highest standards of safety and image quality.
