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.
已设计出一种具有恒定环境温度的微量热计（吸收器温度约为-195摄氏度），其可用于10拉德及以上的剂量。通过使用两种不同电子能量，将该量热计与弗里克剂量计进行对比测量，对硫酸亚铁的G值进行了评估。在24.8兆电子伏时，G值为15.64±0.14离子/100电子伏；在38.8兆电子伏时，G值为15.60±0.13离子/100电子伏。
