A Calorimeter Based on a Resistance Thermometer

摘要

A calorimeter based on aluminum alloy was developed to measure bremsstrahlung doses. The absorbed dose is determined using a thin-wire resistance thermometer included in an electrical bridge. It is shown that state-of-the-art instrumentation is capable of measuring average doses of 0.1 Gy (corresponding to a change of 10{sup}(-4) K in the sensor's temperature) and over.
