Industrial Radiography
Industrial radiography uses ionizing radiation to inspect materials and components, locating and quantifying internal defects invisible to the naked eye.
Radiographic testing works by passing radiation through a test piece onto a detector on the opposite side. Variations in material thickness, density, or composition create differences in radiation intensity that appear as light and dark areas on the resulting image. We use both X-ray generators and gamma radiation sources (Iridium-192 and Cobalt-60) depending on the application requirements.
Our capabilities include traditional silver halide film, computed radiography with phosphor imaging plates, and digital radiography with flat panel detectors. We perform static 2D radiography, real-time 2D fluoroscopy, and computed tomography (CT) for complete volumetric inspection when required.
We employ all standard exposure configurations including panoramic (source centered inside), single-wall single-image, double-wall single-image, and double-wall double-image techniques. Our technicians select the optimal arrangement based on component geometry, material, and applicable code requirements.
The vast majority of our radiography work involves testing and grading welds on piping, pressure vessels, high-capacity storage containers, pipelines, and structural welds. Additional applications include concrete inspection, castings evaluation, machined parts verification, and corrosion detection in operating equipment.
All radiographic operations follow strict safety protocols based on the principle of time, distance, and shielding. Our technicians carry calibrated survey meters, alarming dosimeters, and personnel monitoring devices (TLDs or film badges). We establish controlled and restricted boundaries for every exposure in compliance with NRC and state regulations.
