Rare-earth intensifying screens require films sensitive to which spectrum?

Explanation:
The film must respond to the light that the screen emits. Rare-earth screens convert x-rays to light mainly in the blue-green part of the spectrum, with green being dominant. An emulsion that is sensitive to that blue-green light will record the image most efficiently, giving good speed and contrast. If the film were sensitive only to red or infrared, or to other colors outside that emission range, exposure would be poor and image quality would suffer. So the appropriate sensitivity is the blue-green region.
