Which layer on the PSP plate is responsible for reducing static electricity?

• A. Conductive
• B. Reflective
• C. Phosphor
• D. Insulative

Answer: (A)

Static electricity on a PSP plate tends to build up as the plate is handled, moved, or stored, and this can create image artifacts by attracting dust or causing discharge paths that disrupt the stored latent image. The layer that prevents this buildup is the conductive layer; it provides a path for charges to flow away and be grounded, keeping the plate at a safe potential. The phosphor layer stores the energy from X-rays, the reflective layer helps direct the emitted light to the reader, and an insulative layer would actually trap charges rather than dissipate them. So, the conductive layer is the one responsible for reducing static electricity.
