Abstract

We report on the absolute efficiency of x-ray phosphor screens made of various materials commonly used in the x-ray applications (ZnCdS:Ag - Y₂O₂S:Tb Gd₂O₂S:Tb). All the measurements have been carried out under fluoroscopy conditions for tube voltages ranging from 50kV to 250kV and for screen weights ranging from 15mg/cm2 to 200mg/cm². There is also, for comparison, a set of results concerning the behaviour of the screens under soft x-rays (20kV to 50kV) excitation. All the experimental results are discussed on the basis of a uniform screen model and analytical expressions are presented permitting the theoretical calculation of the absolute efficiency of the screens.
