Air Kerma Strength Measurement of a Cs-137 Source Using a Seven-Distance Ionization Technique
PublicDownloadable Content
open in viewerBrachytherapy describes a process where radioactive sources are inserted directly into the target area of a patient to treat disease. Before they can be used for treatment, brachytherapy sources must be calibrated such that medical physicists know their exact air kerma strength - a quantity given by manufacturers as a standard. Each individual source must be measured before use. Therefore, medical physicists must have an efficient technique for measuring air kerma strength. The goal of this project was to build a system that uses a "seven-distance" ionization measurement technique to measure the air kerma strength of a cesium-137 source. Results obtained using this method were also compared to those obtained using a gamma spectroscopy technique.
