HESI Dental Assisting Exit - Exam Topics Sample Questions

A patient will be exposed to less radiation if the operator uses

Correct Answer:
a faster speed film.


in radiographic imaging, the speed of the film is a crucial factor that impacts the amount of radiation a patient is exposed to during the procedure. film speed in radiography refers to how sensitive the film is to radiation. the faster the film speed, the less radiation is required to produce an image of acceptable quality.

when a faster speed film is used, it requires a shorter exposure time to capture the necessary diagnostic information. this reduction in exposure time directly translates into less radiation being needed, thus minimizing the patient’s exposure to ionizing radiation. faster films have more sensitive emulsions or are enhanced technologically to be more responsive to radiation, which allows them to produce images quickly and with less radiation.

conversely, a slower film speed means the film is less sensitive to radiation. as a result, it requires a longer exposure time or higher doses of radiation to achieve the same image quality as a faster film. this increased exposure is not ideal as it elevates the patient's risk to potential radiation-induced effects, making slower films less preferable in practices aiming to reduce radiation exposure.

the development of faster films is part of the broader trend in radiographic technology towards reducing the radiation dose patients receive. this is aligned with the alara principle (as low as reasonably achievable), which aims to manage and minimize patient exposure to radiation while achieving the required diagnostic outcomes. using faster speed films is a practical approach to adhere to this principle, ensuring patient safety without compromising the quality of diagnostic images.

in summary, choosing a faster speed film in radiographic procedures is a more effective method to reduce the amount of radiation a patient receives. as technology advances, the availability and effectiveness of fast films continue to improve, enhancing both patient safety and the quality of radiographic diagnostics.
