Radiographic Testing Companies

Last updated: January 2026

This directory lists 84 radiographic testing companies across the United States, from dedicated field service providers specializing in pipeline weld inspection to highly specialized labs offering microfocus X-ray for intricate electronics or aerospace components.

Whether you're contending with critical weld integrity on pressure vessels, detecting internal discontinuities in aerospace castings, or performing corrosion under insulation (CUI) surveys, the right RT partner prevents costly failures. Suppliers here help diagnose issues like porosity, lack of fusion, or cracking, ensuring your components meet stringent regulatory and performance standards, often utilizing both X-ray and gamma sources like Ir-192 or Co-60 for optimal penetration based on material thickness and density.

The supplier landscape spans large, multi-discipline NDT firms with extensive geographic reach, smaller, specialized facilities focusing on specific material types or advanced techniques, and independent consultants providing ASNT Level III review and procedure development. Distinguishing between them often comes down to their equipment investment, their personnel certifications, and their ability to mobilize quickly for on-site work versus purely lab-based services.

How to Choose a Company

  • Verify personnel qualifications and certification levels: Demand proof of current ASNT SNT-TC-1A or NAS410 certifications for all technicians, especially ASNT Level II and Level III personnel, who will be interpreting radiographs and approving procedures. A red flag is a provider who is hesitant or slow to furnish these records.
  • Confirm compliance with applicable codes and standards: Ensure the supplier is proficient in the specific codes relevant to your industry, such as ASME Boiler and Pressure Vessel Code (BPVC) Section V for pressure components, API 1104 for pipelines, or ASTM E1742 for general radiographic examination. Ask for their track record of meeting these standards.
  • Evaluate their equipment for your material and application: Determine if their industrial X-ray tubes (e.g., microfocus, high-kV) or gamma sources (e.g., Ir-192, Co-60) are appropriate for the thickness, density, and geometry of your parts. Inquire about their capabilities in Digital Radiography (DR) or Computed Radiography (CR) versus traditional film if turnaround time or digital archiving is critical.
  • Scrutinize their radiation safety program and site capabilities: For on-site radiography, require detailed information on their Radiation Safety Program, their designated Radiation Safety Officer (RSO), and their protocol for establishing a safe work perimeter (e.g., demarcation, exclusion zones). Neglecting this is a common first-time buyer mistake with severe safety and compliance repercussions.

Frequently Asked Questions

What's the trade-off between traditional film radiography and digital radiography (CR/DR)?

Film radiography, while offering excellent resolution and universal acceptance, is slower, requires chemical processing, and necessitates physical storage of films. Digital radiography (Computed Radiography - CR, and Digital Radiography - DR) provides instant image acquisition, eliminates hazardous chemicals, allows for digital image enhancement, and offers easier electronic archiving. DR, utilizing flat panel detectors, is generally faster and can offer superior sensitivity for many applications, though the initial investment in equipment for providers can be higher. CR uses reusable phosphor plates that are scanned, offering a middle ground in terms of speed and cost. Your choice should hinge on resolution requirements, desired turnaround time, and budget.

How do I verify the qualifications of radiographic testing personnel?

Always request documented proof of personnel certification from an accredited body like the American Society for Nondestructive Testing (ASNT). Specifically, look for ASNT SNT-TC-1A or NAS410 (for aerospace) Level II certifications for technicians performing the work, and ASNT Level III certifications for those responsible for establishing techniques, interpreting results, and approving procedures. These certifications attest to their knowledge in radiographic principles, equipment, techniques, and interpretation of indications, ensuring qualified personnel are handling your critical inspections.

What are the key radiation safety concerns for on-site radiographic testing projects?

On-site radiographic testing involves ionizing radiation, necessitating stringent safety protocols. Key concerns include establishing secure exclusion zones to protect personnel from direct or scattered radiation, proper handling and storage of radioactive sources (like Ir-192 or Co-60) or X-ray equipment, and adherence to local, state, and federal regulations (e.g., NRC). A reputable provider will have a designated Radiation Safety Officer (RSO), clearly defined emergency procedures, and be able to demonstrate strict control over their radioactive materials and equipment, minimizing risk to your site and personnel.
