This thesis describes a new method to determine the beta skin-dose and the beta depth-dose distribution from the responses of a multiple-chip thermoluminescent dosimeter (TLD) system. The system is designed for and has been tested in beta radiation fields. The design can be extended to handle mixed beta/gamma fields. The method combines analytical calculations with experimental measurements to reconstruct the incident beta-particle energy distribution. The analysis is performed with an experimentally verified Monte Carlo computer program based on electron-transport theory. The experimental measurements are made with a packet of three LiF TLD chips with thin shields which are exposed to the beta radiation field. The beta doses measured in the TLDs are used to reconstruct the incident beta-particle energy distribution from data tabulated by the Monte Carlo computer program.
