Portable / Backpack Radiation Detection (PGIS-2)

PGIS-2-Backpack_scooter

The PGIS-2 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 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

Acquired data is automatically synchronized with GPS time and location, spectrum can be displayed in real-time in a waterfall/counts per second mode. Data channels: ROI windows, cps; K, U, Th concentrations/activities, dose rate etc. can be displayed in the chart view.

Real time ground navigation allows the operator to follow a survey grid or way-points on a displayed map that can be prepared as a calibrated image (using MAPConvert) or automatically loaded from the Internet (using Open Street Maps).

The PGIS-2 embedded AGRS advanced gamma-ray spectrometer is widely used in geological and geophysical exploration and mapping, as well as in environmental and nuclear surveillance.

Individual and independent detector processing provides real time gain and linearity correction. The AGRS is fully automated and self-stabilizing on natural radioactive elements. This eliminates the requirement for regular and time consuming system checks and recalibration and assures accurate and reliable gamma-ray measurements.

  • 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

PGIS-2 System Description

The PGIS-2 includes detection and acquisition of radioelement data.

DETECTION UNIT

The 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. For communications, it connects to the Data Acquisition via Bluetooth.

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

DATA ACQUISITION

The user interface and data acquisition system is based on the Android™ Operating System, 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 MAPConvert)  for following visualization with GIS applications.
