THE FERROUS-FERRIC DOSIMETER: A REVIEW,
Abstract
The characteristics, preparation, and use of the ferrous-ferric dosimeter are reviewed in detail. This includes a discussion of the dose range, dose rate dependence, energy dependence, and temperature effects. For photons with energies in excess of 6 kev the irradiation yield may be represented by the expression G = 15.61 - 15.43/E, where E is the mean photon energy in kev and G is the number of ferrous ions oxidized per 100 ev of energy absorbed. Several methods of measuring ferric ion concentration are described, including the conventional spectrophotometric determination of ferric and ferrous ion and the very sensitive radiometric measurement of ferric ion. A concise summary of all the information necessary for routine application of this dosimeter is given at the end of the report. (Author)
