The Yield of Oxidation of Ferrous Sulfate in Acid Solution by High-Energy Cathode Rays

Abstract
An absolute determination of the yield of the ferrous sulfate radiation dosimeter has been made by delivering to the solution a measured charge of cathode rays at known energies of 1 or 2 Mev. Appropriate small corrections have been made for backscattering, window absorption and, bremsstrahlung. The result, G = 15.6±0.5, is in complete agreement with Hochanadel's calorimetric determination of the yield, but disagrees by 30 percent with the most widely used value obtained by cavity ion chamber comparison.
