Colorado X-Ray Shielding Design and Certification Evaluation Providers: Qualified Experts and Qualified Inspectors in the Denver and Colorado Springs Front Range
Published 2026-11-07 · Last updated 2026-11-09 · Colorado · qualified expert · qualified inspector · shielding
Providers and facility managers planning a new X-ray room or equipment replacement in the Denver and Colorado Springs Front Range need two separate Colorado registrations: a Qualified Expert for shielding design and a Qualified Inspector for the certification evaluation. These are separate roles. A firm may hold one registration or both. Form R-65 (Notice of Registrant’s Rights) is required before the service or evaluation begins whenever a business relationship exists between the qualified inspector and a registered service company, or between a qualified expert and a qualified inspector.
The authoritative source for current registrations is the CDPHE verification page: cdphe.colorado.gov/hm/xray-registration-verifications. Download the spreadsheet to confirm each individual’s registration type and approved machine categories before you engage them.

How to Use This List with the Facility GuideBack to contents
The shielding-design step in the Colorado X-Ray Facility Guide requires a Colorado registered Qualified Expert before construction or installation of most stationary systems. The certification-evaluation step requires a Colorado registered Qualified Inspector within the timeframe set by Part 2. Form R-65 (Notice of Registrant’s Rights) is required before the service or evaluation begins whenever a business relationship exists between the qualified inspector and a registered service company, or between a qualified expert and a qualified inspector. Using separate companies for design and inspection avoids the form. Confirm every registration on the CDPHE spreadsheet before engaging any provider.
