    Abstract

    This work addresses radiation dose mapping based on scanning of laser heated thermoluminescent foils used for dose distribution analyses of beta radiation fields. Results are presented from dose homogeneity measurements, determination of depth-dose profile in tissue and studies of energy and angular responses of CaSO4:Dy-based TL foils for irradiation in air with beta rays (Pm-147, (TI)-T-204 and Sr-90/Y-90). Laser scanning results are compared with results from measurements using very thin graphite-mixed MgB4O7Dy TL detectors. Results show that detectors based on CaSO4:Dy films will be suitable as extremity dosemeters for monitoring in beta radiation fields.
