[A microcalorimeter for assessment of the G-value of a ferrous sulfate solution for high-energy electrons (author's transl)].
A microcalorimeter with  constant ambient temperature has been designed (circa -195 degrees C = temperature of the absorber), which could be utilized with doses from 10 rd upward. The G-value for ferrous sulfate was assessed by means of comparison measurements with the calorimeter and a Fricke-dosimeter, using two different electron energies. The G-value at 24.8 MeV amounted to 15.64 +/- 0.14 ions/100 eV and at 38.8 MeV, to 15.60 +/- 0.13 ions/100 eV.
