Which practice reduces scatter radiation and exposure to non-target tissues?

• A. Increases exposure to non-target tissues
• B. Increases scatter radiation
• C. Illegally shortens exposure time
• D. Reduces scatter radiation and exposure to non-target tissues

Answer: (D)

Focusing on reducing scatter radiation and protecting non-target tissues comes from limiting where the beam goes and how much energy is delivered. By tightly collimating the beam to the area of interest, you irradiate less tissue overall, which cuts down on photons that can scatter and reach surrounding tissues. Adding appropriate shielding further protects tissues outside the target area and reduces occupational exposure. Using the correct exposure factors and, when needed, grids helps suppress scatter production and improves image quality without unnecessary dose. So, the best practice is to minimize the irradiated volume and apply shielding and proper technique to keep scatter and non-target dose as low as possible. The other options describe actions that increase exposure or rely on unsafe shortcuts, which do not reduce scatter or protect tissues.
