Which type of film is known to use 50% less radiation?

The type of film that is known to use 50% less radiation is higher speed F film. This film can achieve the same level of diagnostic quality as slower films while requiring much less exposure to X-rays. The increased sensitivity of F film is due to its emulsion, which consists of larger crystals that can capture more photons per unit of exposure. This means patients are exposed to significantly lower levels of radiation during dental imaging while still obtaining clear and accurate images for diagnostic purposes.

In contrast, standard speed D film requires a higher dose of radiation to achieve adequate image quality, which can lead to increased radiation exposure for patients. Ultra speed E film also offers lower radiation exposure than D film but not as significantly as F film. Digital film, while eliminating the need for traditional film and therefore offering instant images, works differently by converting X-ray images into digital format electronically, which can also reduce overall radiation exposure. Nonetheless, higher speed F film is specifically designed for reduced radiation liability.
