Scatter Radiation Compensation Filter
A stray radiation compensation filter reduces interfering secondary radiation in radiographic testing, improves contrast, and increases inspection accuracy.
Physicochemical mechanism of action
A scatter compensation filter absorbs or diffracts interfering secondary rays that occur during radiography. This reduces noise in the image and increases the visibility of the material being tested.
Metallurgical relevance & risks in welding
Without a compensation filter, secondary radiation can lead to inaccurate or false test results. This can cause errors in quality assurance and in checking for cracks or material defects, posing risks to safety and operation.
Workshop practice & instructions
Use a scatter compensation filter with an absorption coefficient of at least 90% to reduce secondary rays. Make sure the filter is regularly maintained and clean to ensure optimal performance.
