Description
This work showcases the development and performance of a novel IoT-based dosimetry system for real-time measurement of ambient dose equivalent H*(10) and personal dose equivalent Hp(10), developed within the ODIS project and characterized under EBDIZ project.
The detector system is based on a scintillation crystal with an energy response optimized (compensated) through tailored adjustment of its composition. The scintillation light is collected by a silicon photomultiplier (SiPM). A fully customized electronic architecture has been developed, including a dedicated SiPM power supply, a low-noise front-end amplifier, and an innovative dead-time-free analog-to-digital converter.
The system enables measurements over an exceptionally wide dynamic range spanning eight orders of magnitude—from natural background radiation levels up to dose rates on the order of Sv/h. Performance characterization includes evaluation of linearity, dynamic range, and energy response.
The digital subsystem performs on-board data processing and transmits measurement data to an IoT gateway with a communication range of up to 10 km. The gateway forwards the data to a dedicated IoT platform, where results are accessible via a web interface, mobile application, or application programming interface (API), enabling scalable real-time radiation monitoring.
