Intensifying screen emulsion on both sides includes which combination?

Intensifying screen emulsion on both sides includes which combination?

• A. Gelatin
• B. Silver compounds
• C. Gelatin, silver compounds, protective coating
• D. Protective coating

Answer: (C)

In radiographic film emulsion, the layer that records the image is a gelatin-based matrix in which silver halide crystals (the silver compounds) are suspended. Gelatin serves as the binder that holds these tiny light-sensitive grains in place, allowing the latent image to form when exposed and then be developed into a visible image. For film designed with emulsion on both sides, this structure is present on each surface to increase sensitivity. The outermost surface is a protective coating that shields the delicate emulsion from abrasion and moisture, helping maintain image quality during handling and processing. Therefore, each side consists of gelatin, the silver compounds, and a protective coating.
