PoliPack® GN-S Backpack Radiation Detector

New Backpack Radiation Detector Radionuclide Identification Device On order
PoliPack GN-S

Spectroscopic Gamma-Neutron Backpack Radiation Detector.

The PoliPack® GN-S is a gamma-neutron Backpack-Based Radiation Detection System (BRD) equipped with spectroscopic gamma detectors for identifying radionuclides. It is carried in a compact backpack and controlled remotely via the wired control unit or a smartphone with the free Polismart® iOS and Android App.

The PoliPack® BRDs are rugged, lightweight, and fast deployable devices that provide prompt and reliable detection, location, and identification of multiple and masked isotopes. The device is ideal for undercover radiation surveys in crowded areas, addressing the problems of orphaned and maliciously introduced sources and ensuring security before and during mass events. Radionuclides libraries are uploaded in the BRD and can be customized by users.

Features

  • ANSI N42.53-2021 and IEC 62694:2022 compliance
  • ANSI N42.42 format data transmission
  • Indication of the direction to the source
  • Radionuclides identification in less than 1 minute 
  • Categorization of identified radionuclides 
  • Adjustable radionuclide libraries
  • Long-life rechargeable battery for 72 hours of operation
  • The housing design ensures device floats in water
  • Operable in stationary mode with mains power 
  • Wired (remote control) and wireless (Polismart® App) display 
  • Optional extended range detector for dose rate up to 10 Sv/h
  • USB and Bluetooth communication

Applications

  • Mapping of contaminated areas 
  • Safety of critical infrastructure 
  • Public events security 
  • Emergency services 
  • Homeland security

Operation principle

The PoliPack® BRD basic operation mode is the Search mode, which has different task-oriented screens allowing to detection of the presence of radiation, monitoring the gamma radiation dose rate, indicating the direction of the source, and identifying the detected radionuclides.

Polimaster BRD is compliant with the ANSI N42.53-2021 and IEC 62694:2022 standards. Its transmission data format is designed to meet the ANSI N42.42.

The BRD has two log-on access modes: Simple and Expert. The Simple default access allows a user to perform all the tasks needed for the routine operation of the instrument. The Expert PIN-protected advanced access allows an experienced operator to control the parameters that can affect the result of a measurement (radionuclide library, alarm thresholds, etc.).

Add-ons

The BRD can be equipped with an external gamma detector based on a GM tube for an extended dose rate measurement up to 10 Sv/h.
