PGIS-2

PGIS 2 is a portable gamma spectrometer designed for field radiation monitoring and mobile gamma spectroscopy. Its compact detection module with a 3″×3″ (0.347 L) NaI(Tl) crystal provides high sensitivity across the 50 keV–3 MeV energy range.

The system uses digital signal processing (DSP/FPGA) with an 8196 channel MCA, real time automatic stabilization, digital baseline restoration, and pile up rejection below 40 ns, ensuring accurate spectral reconstruction and virtually zero dead time even at high count rates.

Measurement control and data acquisition are handled via an Android™ based data logger with integrated GPS synchronization, enabling real time spectrum display, data storage, and export to standard formats (CSV, GIS, XML, ANSI N42.42). Text and multimedia notes can be attached to individual measurements for enhanced field documentation.

PGIS 2 provides automatic radionuclide identification according to ANSI N42.42 and supports navigational field surveys. With its integrated Li Ion battery offering a typical 24 hour runtime and a total weight of approximately 5 kg, the system is suitable for handheld or backpack use during radiation surveys and rapid inspection tasks.
