Personal dosimetry geolocalized system for radiation monitoring

A geolocalized radiation monitoring system has been developed based on a small and portable personal dosimeter. This dosimeter uses a scintillator-SiPM combination for the radiation detection; it includes spectroscopy and isotope identification capabilities. The personal dosimeter uses a 9×9×20mm
³
CsI:Tl crystal and a 50μM SiPM. All measurements are time and location stamped, even for indoor locations. The system is designed in such a way that different wireless connectivity options are available. It can use Bluetooth, WiFi, GSM, etc. depending on the application, and it also has the option of connecting to a mobile phone. When used for radiation monitoring over wide areas several networked dosimeters can provide a high sampling rate over an extended area simultaneously on fixed or mobile platforms. Three elements comprise the complete system: the dosimeters, a wireless gateway and a web-based remote storage, monitoring and management system (central system).
