title: Energy dependence of correction factors for the Victoreen Model 666 Portable Radiographic Health Survey System.
abstract: The energy dependence for each of three models of Victoreen 666 ionization chambers is characterized through an examination of the correction factors determined over the diagnostic x-ray range (0.4-4.9 mm A1 HVL) for many samples of each model. The results of an analysis of variance performed for each chamber model on the correction factors are reported as mean correction factors for the x-ray beams evaluated, with a relative standard error of less than 0.6% in all cases. Energy-dependence curves for the three chamber models are given, and their use is described.
