[2025-10-02T06:27:24.542394] [PI reasoning] **Identifying disadvantages in radiography grids**

The question is about the disadvantages of using grids in radiography, which are primarily used to reduce scatter radiation. Main concerns include increased patient dose from higher exposure factors, the need for precise alignment, artifacts from grid lines, and added weight. For the options given, A mentions skin exposure, which implies increased dose and is indeed a disadvantage. B relates to increased exposure time, which is another drawback. However, I’d highlight "skin exposure of patient" as a significant disadvantage overall.
