What is a common type of phosphor?

• A. Calcium Tungstate
• B. Radiolucent
• C. Acute Radiation Exposure
• D. Automatic Processor

Answer: (A)

Phosphors are materials that luminesce when they’re struck by X-rays, turning that radiation into visible light to expose the film in radiographic screens. Calcium tungstate is a classic example of a phosphor used in these screens because it emits light when hit by X-rays, helping to produce an image while reducing the amount of radiation needed. The other options aren’t phosphors: radiolucent describes a material that X-rays pass through easily, acute radiation exposure is a radiation dose condition, and an automatic processor is a device that develops film. So calcium tungstate fits as a common phosphor.
