What type of film is likely to decrease radiation exposure?

High-speed film is designed to be more sensitive to radiation, which means it requires a lower dose of radiation to produce a diagnostic image. This increased sensitivity allows for quicker exposure times, therefore reducing the amount of radiation that both the patient and the dental professional are exposed to during the imaging process.

In contrast, standard or slow films require more exposure to radiation to achieve a similar level of image quality, which results in increased radiation doses. Advanced film may refer to newer technologies that could similarly reduce exposure, but high-speed film specifically is well-documented for its efficiency in lowering radiation levels necessary for effective imaging. Thus, high-speed film is recognized as the type that effectively decreases radiation exposure in dental radiography.
