Scatter Radiation Compensation in Radiography

Physicochemical mechanism of action

Scattered radiation is created by reflection and absorption of primary rays on materials in the X-ray image. This unwanted radiation can contaminate the image and reduce contrast.

Metallurgical relevance & risks in welding

When checking weld quality with X-rays, high scatter values can lead to unclear images, making it harder to detect flaws. This can cause misunderstandings and potential defects.

Workshop practice & instructions

Use special filters or software to reduce scatter. Set the parameters so the signal-to-noise ratio is optimized (e.g., an SNR of at least 10:1). Regularly check image quality and adjust settings accordingly.
