NettetIntensifying screen: These screens are fitted in x-ray cassettes and interact with x-rays to convert most of their radiant energy (>95%) in to visible light thereby, exposing the x-ray film finally with light (and not the x-rays). The amount of light emitted by the intensifying screen is proportional to the amount of x-radiation passing through it. NettetAn intensifying screen is a plastic sheet coated with fluorescent material called phosphors. Phosphors are materials which convert photon energy to light. The x-ray energy is absorbed by the intensifying screen material, and a portion of it converted into light.
