This instrument is designed for portable or backpack application for radiation detection and monitoring in a variety of environments.

The system is auto calibrated by natural photo peaks, consisting of a detector unit, integrated with GPS, and a data logger unit (PEICore) based on state-of-the-art Android portable devices, such as a smart-phone, a tablet or a notebook. The detector can be equipped with a NaI(Tl) crystal of various volumes ranging from 0.347 liter up to 2 liters.

The PGIS-2 provides continuous time and location synchronized data acquisition, recording of a full spectra, real-time dose calculation from spectra, isotope detection capabilities, visual and audible alarming of preset events, stationary data accumulation and synchronized comments that send data to the server option

The system is suitable but not limited to the following applications:

  • Social Events Security Monitoring (Sporting Events, Concerts, Public Meetings, Festivals, etc.)
  • Indoor and Outdoor First Response HAZMAT
  • Public sites and facilities undercover monitoring
  • Contaminated areas detailed study and mapping
  • Detailed area monitoring and background radiation mapping
  • Small scale search and recovery of unattended radioactive sources
  • Potential radiological threat identification
  • Radiation protection and control tasks

Typical PGIS-2 System Description


A standard Detection Unit consists of a large effective volume NaI(Tl) scintillation crystal (either 0.347, 1 or 2 Liters), GPS and supporting electronics. The Detection Unit can be customized with GM tube and Neutron detector. The Detection Unit standard is set in a rugged plastic case with a handle. The Detection Unit is connected to the Data Acquisition via Bluetooth.

The system is self-calibrated and energy stabilized in real-time.


The user interface and data acquisition system is based on the Android™ OS (DAQ, PEICore), allowing the operator to control surveillance parameters, including map-view navigation, real-time data acquisition, and real-time spectra in a chart or waterfall view. The Audio and/or Visual alarms can notify the operator of a potential threat. A notification can be forwarded to the reachback center.

The collected data is ready for mapping and reporting right after a mission. The data can be exported to ASCII, Binary or KMZ format (using PEIConvert)  for following visualization with GIS applications.
