A portable thyroid dose monitoring system using gamma-ray spectrometers has been developed in JAEA. In this presentation, the results of performance tests of candidate detectors (CdZnTe detector and LaBr₃ / SrI₂ scintillation detectors) and optimization of radiation shield’s design will be described.
