Excerpt from The Construction of Calorimeters for the Measurement of Absorbed Dose It is generally conceded1 that an important parameter to correlate with the effect of radiation on matter is the energy locally absorbed. In 19532 the International Commission on Radiological Units and Measurements called this quantity absorbed dose and its unit the rad (equal to 100 ergs per gram in the material of interest). Methods for determining the magnitude of the a sorbed dose have been outlined by this group in later publications}, The ionization method, because of its high sensitivity and its long usefulness has been treated in some detail by this group. However, the calorimetric method is an alternative and more direct technique, if the dose rate is high enough.
