What does the term ‘scatter radiation’ refer to?

Scatter radiation refers to radiation that has been deflected from its original path due to interaction with matter. In the context of industrial radiography, when gamma rays travel through materials, they can collide with atoms in those materials and lose energy, changing direction in the process. This change in direction is what defines scatter radiation.

Understanding scatter radiation is crucial for safety in radiographic operations, as it can pose a risk to personnel and lead to inaccurate readings if not accounted for properly. Additionally, recognizing how and why scatter occurs helps radiographers to implement effective shielding and safety protocols during inspections. The presence of scatter radiation is an essential aspect of interpreting radiographic images and ensuring the reliability of testing results.
