Radiographic Scatter Radiation Grid Technique
Radiographic scatter reduction grid technique uses lead strips to reduce secondary radiation and improve image contrast for thick-walled components.
Physico-Chemical Mechanism of Action
Radiographic scatter radiation grid technique uses lead strip collimators that absorb secondary radiation. This minimizes noise in the image and increases the visibility of defects.
Metallurgical Relevance & Welding Risks
Reducing secondary radiation improves the precision of radiography. Without collimators, the image can be too unclear and flawed, leading to misjudgments.
Workshop Practice & Action Guidelines
Use lead strip collimators with a thickness of 0.5 to 1 mm. Place the collimators between the test piece and the detector. Ensure the collimators are aligned straight to get a uniform image.
