Anti-scatter grid

Stray radiation grid consists of absorbing slats that reduce secondary radiation in radiographic testing. It improves contrast and image sharpness.

Physikalisch-chemischer Wirkmechanismus

A scatter grid consists of absorbing lamellae that absorb secondary radiation, thereby reducing the intensity of the radiation. This improves the contrast in the radiographic image.

Metallurgical Relevance & Welding Risks

If the scatter grid is missing or defective, the secondary radiation can be uncontrolled, leading to a blurrier image and poorer contrast. This can cause problems in detecting flaws and cracks.

Werkstattpraxis & Handlungsanweisungen

Make sure the scatter grid is correctly mounted and the lamellae are clean. Incorrect mounting or contamination can lead to inaccurate results. If necessary, perform a calibration to check the image quality.
