Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water calorimetry. Since the dose distributions delivered by such beams are nonuniform, temperature signals generally exhibit distortions due to heat conduction and convection, making it necessary for the determination of appropriate correction factors. COMSOL Multiphysics enabled us to understand the origin of various phenomena we observe in the cell and helped estimate the associated correction factors.
