Starck. Calcium tungstate occurs in nature as scheelite and is among the most important luminophores, i.e. when it is exposed to x-rays, it appears blue.

Rare-earth and calcium tungstate intensifying

Using calcium tungstate (CaWO4) and rare-earth intensitying screens, their relative speeds were compared in exposures of a pelvis phantom, and radiation doses were measured at several kilovoltages. Using a slit pattern, the resolving power was assessed by a modified contrast-frequency response and by direct viewing of the radiographs.Rare-Earth Screens Versus Calcium Tungstate,If the address matches an existing account you will receive an email with instructions to reset your passwordblue green Intensifying screens permit a good,Intensifying screens permit a good radiograph to,Standard screens use calcium tungstate phosphors, while rare earth screens use
