What type of film is primarily used in traditional radiography?

In traditional radiography, the primary type of film utilized is X-ray film. This film is specifically designed to be sensitive to the ionizing radiation produced by X-ray machines, allowing it to capture the images that are necessary for diagnostic purposes.

X-ray film is coated with a photo-sensitive emulsion that reacts to radiation exposure, creating a latent image that is later developed into a visible image. This unique characteristic makes it suitable for capturing detailed images of the body's internal structures, such as bones and organs.

In contrast, color film is primarily intended for photography, not for medical imaging, as it does not meet the specific requirements for capturing X-ray data. Slide film is designed for projecting images, and while negative film might capture images that can be later developed, it is generally meant for visible light and not for the high-energy radiation used in X-ray procedures.
