Which type of light do rare earth screens emit?

Rare earth screens primarily emit green light when stimulated by X-ray radiation. This is due to the phosphor materials used in the screens, which have been designed to efficiently convert X-rays into visible light, particularly in the green spectrum. The green light emitted is beneficial because traditional X-ray film is more sensitive to green light, allowing for improved image quality and reduced exposure times. This characteristic makes rare earth screens a preferred choice in dental radiography as they enhance the imaging process while minimizing patient radiation exposure. Furthermore, the use of green light can contribute to better contrast in the images captured, leading to more accurate diagnoses.
