INTERCOMPARISON MEASUREMENTS OF EXTREMITY DOSEMETERS IN BETA AND/OR PHOTON RADIATION FIELDS

摘要

Beta dosimetry, especially at the extremities, is gaining in importance due to the increasing use of beta particle sources, e. g. in brachytherapy. The dosimetric properties of personal dosemeters to be worn on the extremities and capable of measuring the personal dose equivalent, H_p(0.07), in beta and/or photon radiation fields fields were investigated within the scope of intercomparison measurements organised by the PTB in two steps. The results were evaluated on the basis of recommendations from the German Commission on Radiologicla Protection (SSK).
