Studies of Excess Heat and Convection in a Water Calorimeter
Abstract
This paper discusses model studies and analyses to estimate systematic effects in water calorimetry for measuring absorbed radiation dosage. The importance of measuring absorbed dose in water, Dw, and its significance to radiation therapy has been stated in many publications and will not be repeated here. The reader is referred to an excellent review on water calorimetry for radiation dosimetry by Ross and Klassen [1]. Water calorimetry is based on the assumption that the temperature rise at a point in water, deltaTau(w), produced by radiation alone, with no transfer of heat to or from that point, is given by: D(w) = C(w) . DeltaTau(w), where C(w) is the specific heat capacity of water at the operating temperature of the calorimeter, and D(w) is the energy per unit mass imparted to matter at a point by ionizing radiation.
