How does radiography work in NDT?

Radiographic testing in NDT works by directing X-ray or gamma radiation through a component onto a detector, rendering an image that reveals internal features and discontinuities based on variations in material density and thickness. Areas such as cracks, porosity, or inclusions absorb radiation differently, making defects visible in the resulting image. Depending on inspection requirements, radiography can be performed using several techniques, including Film Radiography, Computed Radiography (CR), Digital Radiography (DR), and Computed Tomography (CT), each offering varying levels of image quality, speed, and data output.

Radiographic inspection in Non Destructive Testing

Radiographic Testing (RT) is an NDT method used to examine the internal condition of a component by passing X-ray or gamma radiation through the material. The resulting image reveals internal defects such as cracks, porosity, or inclusions undetectable from the surface. RT is valued for its ability to provide clear visualization of subsurface flaws, though it entails strict safety controls due to the use of radiation.

RT inspection systems and equipment delivered by ATG

ATG collaborates with providers of radiographic (RT) solutions in the field of Non-Destructive Testing (NDT) and contributes to the delivery of comprehensive systems and equipment for industrial applications. The offered solutions include advanced radiographic inspection technologies tailored to specific customer requirements, with a focus on image quality, operational efficiency, and compliance with applicable safety and regulatory standards.

 

ATG ensures technical integration of the systems into production and inspection processes, supporting implementation, workflow optimization, as well as ongoing maintenance and service.

RT equipment: X-ray sources ATG FOKUS

Portable X-ray sources FOKUS XD (direct 160 and 200 kV) and FOKUS XP (panoramatic 200 kV) have small dimensions and weight from just 5.4 kg – type XD160. They are therefore one of the smallest X-ray sources with constant power in their class. These sources are designed to work with 230V from the power grid, 24V battery, or a 12/24V converter. The whole set is delivered including a cooler (ventilation fan) that can be placed directly on the source’s main body.

Key features of ATG FOKUS:

RT equipment: SCANRAY

Industrial detector line, ScanRay, are produced in cooperation with a worldwide producer and are intended for use in NDT, with a possible load of up to 450 kV (depending on individual type). Important advantage of these flat panels is quick access to the final radiograph – compared to film radiography the time is approximately one third.

Qualification of NDT operators for Radiographic testing

The deliveries of radiographic systems are joined with the possibility to qualify NDT operators and provide on-the-job training in the ATG Training Center where there is dedicated RT training equipment. Operators can also be qualified directly on the equipment delivered to and at the customer’s site.

Frequently Asked Questions (FAQ)

What is Digital Radiography (DR) in NDT?

Digital Radiography (DR) is a radiographic testing method that captures inspection images directly using a digital detector. Incoming radiation is instantly converted into electrical signals, which are processed into a digital image. Because the image is created almost immediately, DR enables near real-time inspection and faster evaluation compared to traditional and computed radiography.

Computed Radiography (CR) is a radiographic testing method that replaces traditional film with reusable phosphor imaging plates. These plates store the radiation image, which is later scanned by a laser and converted into a digital image for evaluation on a monitor. CR often serves as a transitional technology between film radiography and fully digital radiography, combining familiar workflows with digital image processing.
Radiographic Testing offers reliable volumetric inspection by providing a clear visual image of internal structures and defects within a component. It is applicable to a wide range of materials and allows inspectors to detect variations in thickness and density with high sensitivity. Another key benefit is that RT creates a permanent inspection record, enabling results to be reviewed, archived, and compared over time.
Radiographic Testing is a relatively expensive NDT method. It requires access to both sides of the component, which can make inspections of complex geometries challenging. Very small defects or certain orientations of flaws may be missed. The method relies on highly trained personnel to operate inspections correctly and safely.
X-rays are a form of ionizing radiation generated in a tube, where high-speed electrons are suddenly stopped by a tungsten target, producing both heat and X-ray photons. Unlike gamma rays, the intensity and energy of X-rays can be precisely controlled, making them adjustable for different inspection requirements.
In radiographic testing, gamma rays pass through the material being inspected and are absorbed differently depending on the density and thickness of the material. Defects like cracks, voids, or inclusions allow more radiation to pass through, creating a contrast on the detector or film that reveals internal flaws. Gamma rays are especially useful where portable inspections are needed and electrical power for X-rays is unavailable.

In the energy industry, RT is extensively used to inspect welds, pipelines, storage tanks, and other critical components. By detecting internal defects, flaws, and corrosion, radiography ensures the integrity and safety of power plants, nuclear facilities, and oil & gas infrastructure.Inherently helping to prevent failures and maintain compliance with strict safety standards.

Yes, portable motorized manipulators are available. For example, for testing membrane walls of boilers, our RT solution RTM MW 2000 can be used – an automated manipulator specifically developed for the radiographic testing of boiler membrane walls. This system increases inspection efficiency two-to-threefold and enables evaluation from a safe zone. The inspection of the images generated must ultimately be performed by a human.
