title: An ice calorimeter for photon dosimetry.
abstract: A prototype absorbed-dose ice calorimeter has been constructed of ice made with triple-distilled water. The calorimeter was formed by sandwiching a thermistor between two blocks of ice. Initial measurements in a 60Co gamma-ray beam show that ice calorimetry is feasible, giving a signal to noise ratio of about 300 for a dose of 5 Gy.
