The presence of which gas could interfere with the quality of a radiograph?

The presence of oxygen can interfere with the quality of a radiograph due to its reactive nature. In radiographic testing, the primary goal is to obtain clear and precise images of the internal structure of a material or component. Oxygen can oxidize materials during exposure, leading to the formation of oxidation products that may create artifacts or unwanted contrasts in the image. These artifacts can obscure the true structure being examined, thereby compromising the interpretation of the radiograph.

In radiographic environments, maintaining control over the atmospheric conditions, including oxygen levels, is essential to ensure high-quality imaging and accurate detection of flaws or defects within the tested materials. Proper handling and usage of shielding or inert gases can mitigate the adverse effects caused by oxygen and enhance the reliability of the radiographic results.
