Two important physical characteristics of x‐ray intensifying screens, speed and resolution, are inversely related. However, the exact mathematical relationship, if any, between them is not known. To investigate this matter, a simple model is considered, which predicts that the product of the equivalent passband N e and the square root of the speed is constant for a given phosphor material and given film. This relationship is found to be in excellent agreement with experimental data. The paper concludes with a discussion of the generalized validity of this relationship.
