The objective of this study was to characterize the latest version of the electronic D-Shuttle dosimeter (Chiyoda Technol Corp., Tokyo, Japan) for potential use in dosimetry of members of the public. The investigations comprise: (a) reproducibility, batch homogeneity, dose linearity, dose rate and angle dependence, and radiation hardness using irradiations at the secondary standard dosimetry laboratory of the Paul Scherrer Institute (PSI); (b) estimation of the environmental dose rate and its variability; and (c) feasibility tests for guests at PSI (short-term researchers). The performed verification measurements showed overall a good reproducibility, maximum 1.4% standard deviation (sd) per dosimeter, and maximum 1.0% sd for 5 dosimeters, in agreement with the manufacturer's specifications. The deviation from linearity was <10% and the deviation with energy was <30% in the range [60 keV, 1.25 MeV], except for 164 keV photons (N-200 radiation quality), where a deviation of almost 50% was observed with respect to the Cs-137 radiation quality. The angle dependence was within specifications (±10%) for Cs-137, but up to +30% for 83 keV photons (N-100 radiation quality). The drop in response for dose rates >0.5–1 mSv/h was well described by an inverse polynomial function, and no influence of a high dose irradiation (16.37 Sv) in subsequent low dose measurements was observed. Environmental background (BG) measurements demonstrated that the dosimeters are stable, showing a mean background indication of (70 ± 30) nSv/h, where the standard deviation is compatible with Poisson statistics assuming a sensitivity of 1 count per 10 nSv. This means that hourly indications above 220 nSv/h (BG + 5 sd) can be clearly distinguished from the background. The monitoring of the guests activities showed that the high sensitivity and hourly information can be useful to investigate out-of-the-ordinary exposures, representing a valuable tool for radiation protection of members of the public.
