    Correct Answer
    A. Conventional radiograpHy
    Explanation
    Conventional radiography refers to the traditional method of capturing and processing X-ray images using film and chemical processing. This method involves exposing the patient to X-rays, which pass through the body and create an image on the film. The film is then developed in a darkroom using chemicals to produce the final image. In contrast, digital radiography uses electronic sensors to capture X-ray images, which can be viewed and manipulated on a computer. Therefore, the given answer "conventional radiography" is the correct choice as it is the traditional method in the imaging chain.

    Which layer of the radiographic film is sensitive to radiation and light, thus capturing the image?

    • A.

      Base

    • B.

      Emulsion

    • C.

      Protective coating

    • D.

      Adhesive layer

    Correct Answer
    B. Emulsion
    Explanation
    The emulsion layer of a radiographic film contains silver halide crystals suspended in gelatin, which are sensitive to both light and radiation. When the film is exposed to light (from an intensifying screen) or direct radiation, the silver halide crystals undergo a chemical change. This change is later developed into a visible image. The emulsion layer is the key component in capturing and recording the radiographic image.
