Final answer:
An intensifying screen is a device used in radiography to convert x-ray energy into visible light. This screen, often combined with an x-ray film, exposes the film to visible light produced from the absorbed x-rays, creating a discernable image for medical professionals.
Step-by-step explanation:
The device that transfers x-ray energy into visible light is termed an intensifying screen. In the field of medicine and radiography, X-rays are used to visualize the internal structures of the human body. These X-rays are high-energy electromagnetic radiation capable of penetrating solids. While this radiation works well in medical diagnostics, it can be harmful if the exposure is too high.
When X-ray films are used in medical diagnostics, they're often combined with a device called an 'intensifying screen'. This device works by converting the X-ray energy into visible light. The intensifying screen consists of phosphor crystals that fluoresce as they absorb the X-rays, producing light. This light then exposes the film. The radiation is thus turned into a visible image on the film, which can be interpreted by medical professionals.
It's important to note that the process is not 100% efficient; not all incidence radiation interacts with the screen and produces light. However, intensifying screens significantly boost the efficiency of the process and reduce the amount of radiation to which the patient is exposed.
