Which statement is true regarding the sensitivity of non-screen film in comparison to screen x-ray film?

• A. Non-screen film is more sensitive to light
• B. Non-screen film requires less radiation to produce an image
• C. Non-screen film is more sensitive to x-rays
• D. Non-screen film produces images with more detail

Answer: (C)

Non-screen film is known for its higher sensitivity to x-rays when compared to screen x-ray film. This characteristic allows non-screen film to capture images with less radiation exposure, which can be beneficial in certain diagnostic imaging situations. The x-ray photons interact directly with the film emulsion, producing a latent image. In contrast, screen film relies on a phosphorescent screen to convert x-ray energy into light, which then exposes the film, making it less directly responsive to x-rays. By being more sensitive to x-rays, non-screen film enables the possibility of using lower doses of radiation, making it advantageous in scenarios where minimizing patient exposure is a priority. Additionally, while non-screen film can produce images with fine detail, this isn’t the primary aspect that distinguishes it from screen film in this context. Focusing on its direct interaction with x-rays clarifies why this statement is particularly relevant in discussions of film sensitivity and imaging efficiency.
