Radiographic Inspection Services
View Your Material from the Inside, to Ensure Quality Composition
With radiography, you can use X-rays to view inside objects, determine thickness or composition of material, and detect discontinuities in the material.
TÜV Rheinland provides experienced, qualified employees with numerous hours of training in radiation inspection, including on-the-job training – ensuring an accurate and safe work environment. All radiographers are certified in accordance either to American Society for Nondestructive Testing (ASNT) or EN (European Norms) standards and are capable of providing quality accurate films and readings. Our high-quality, state-of-the-art equipment provides exposures quickly and accurately.

The part in question is exposed to radiation. The image is transposed to either film or a digital detector, which can be utilized to detect and measure the density of the material – the variations in the densities will show up as discontinuities or flaws in the product.
To see through complex parts, a varying amount (or intensity) of radiation is used to determine exact thicknesses and detect discontinuities in the material being exposed on the film or digital plate. This process can be performed through different methods of exposure (for example, real-time, gamma, or x-ray tube), depending on the density and thickness of the product in question.
The data can be stored either on film or a digital image, and the images can then be viewed and compared to a set of standards (ASTM or DIN) to verify acceptable versus rejectable parts. Through viewing the variations in density that appear in a black-and-white contrast on film or a series of differing color contrast on the digital images, the trained certified inspector is able to read and grade the films and then determine if parts are acceptable or rejectable.
Radiography is the use of X-rays on cross-materials to view inside objects. A heterogeneous beam of X-rays is produced by an X-ray generator and is projected toward an object. According to the density and composition of the different areas of the object, a portion of the X-rays are absorbed by the object. The X-rays that pass through are then captured behind the object by a detector (film sensitive to X-rays or a digital detector), which gives a two-dimensional representation of all the structures superimposed on each other.
Detected and measured to determine the density of the material, variations in this amount (or intensity) of radiation are used to determine thickness or composition of material and detect discontinuities in the material.
