Gamma-only Backpack Radiation Detector.
The PoliPack® G is a gamma-only Backpack-Based Radiation Detection System (BRD) equipped with a highly sensitive portable radiation monitor 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-deploying 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.
Features
- ANSI N42.53-2021 and IEC 62694:2022 compliance
- ANSI N42.42 format data transmission
- Indication of the direction to the source
- 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.).
