Gamma–Neutron Search Backpack

Covert backpack, dual-radiation reach

The PoliPack™ GN is a gamma–neutron backpack radiation detector for Australian CBRNe units, police, border teams, and event security. Gamma and neutron detectors, batteries, and electronics are hidden in a civilian-style pack, while a wired handheld controller and Polismart® smartphone app give operators live search, dose-rate, neutron, and direction-to-source views.

Modular hardware, including an optional extended-range GM probe, Bluetooth® connectivity, and standards-based data export, supports an end-to-end workflow from covert patrol to mapped, shareable evidence.

Why Teams Choose PoliPack™ GN?

• Dual-modality coverage: CsI(Tl)+SiPM gamma detector and ^6LiF/ZnS neutron detector tracks both photons and neutrons in one platform.
• Faster localisation: Search-focused screens and direction-to-source indication reduce time from first alarm to locating the source.
• Rugged and water-ready: IP67 rating, 1 m drop rating, and floating design support deployments in wet, hot, and coastal Australian conditions.
• Endurance & flexible power: 6400 mAh Li-ion pack delivers ≥72 hours of operation, with mains-powered stationary mode for ad-hoc fixed monitoring.
• Standards-based trust: Designed around ANSI N42.53, IEC 62694, and ANSI N42.42 data format to align with agency, regulator, and integrator expectations.

Frequently Asked Questions

What radiation types does PoliPack™ GN detect?

PoliPack™ GN simultaneously detects gamma and neutron radiation. It measures gamma dose-rate, logs neutron count-rate, and supports spectral logging for more detailed analysis via Polimaster software.

How rugged is the system for real-world operations?

The GN is IP67-rated, drop-tested to 1 m, and designed to float if immersed. It runs from –20 to 50 °C and in high humidity, making it suitable for most Australian field, maritime, and bad-weather deployments.

What devices can I use to operate PoliPack™ GN?

Operators can use the wired handheld controller for direct alarms and control, and connect via Bluetooth to the Polismart® app on iOS or Android for live dashboards, GPS-referenced tracks, configuration, and data export.

Does PoliPack™ GN provide radionuclide identification?

The PoliPack BRD family supports spectra acquisition and analysis, but full spectroscopic radionuclide ID is explicitly documented for the GN-S model.
