Handheld Gamma–Neutron Detector and Personal Dosimeter

One-pager for search and personal safety

The PM1703GNA-II MBT is a gamma–neutron PRD and personal dosimeter for border teams, responders, and security units who need both interdiction and dose control in one tool. A CsI(Tl) + SiPM search channel, a ^6LiF/ZnS neutron detector, and a GM tube for Hp(10) dose up to 10 Sv sit in a single pager-style body.

With modular AA-powered hardware, USB and Bluetooth® 4.0, plus the Polismart® companion app, you get an end-to-end workflow from fast source detection to GPS-tagged dose history, exports, and audit-ready reporting.

Why Teams Choose PM1703GNA-II MBT?

• True dual-modality safety: CsI(Tl) gamma, ^6LiF/ZnS neutron, and a GM tube: find sources and track personal Hp(10) in one pager.
• High-range dosimetry: 0.1 µSv/h to 200 mSv/h and up to 10 Sv dose: covers routine patrols and serious incidents with one platform.
• NORM-smart interdiction: NORM suppression and IND/NUC/MED classification: fewer nuisance alarms, clearer decisions at ports and yards.
• Rugged, low-fuss hardware: IP65, –40 to +50 °C, up to 98% RH, and AA power: no docking cradles needed, built for hard Australian environments.
• Connected workflows: USB plus Bluetooth with Polismart® app and PC software: GPS mapping, 2000-event history, and ANSI N42.42-style exports for command and control.

Frequently Asked Questions

What radiation does the PM1703GNA-II MBT detect?

It detects gamma radiation from 33 keV to 3 MeV via a CsI(Tl) detector and GM tube, and neutrons from thermal up to about 14 MeV via a ^6LiF/ZnS detector, giving full gamma–neutron coverage.

How is MBT different from the PM1703GNA-II BT?

The BT model is a PRD with a dose rate up to 300 µSv/h and no integrated Sv dose. The MBT adds a GM tube so it can measure up to 200 mSv/h and accumulate Hp(10) dose up to 10 Sv, acting as both PRD and personal dosimeter.

Is the device rugged enough for Australian field conditions?

Yes. It is IP65-rated, operates from –40 to +50 °C and up to 98% relative humidity, uses a shockproof sealed housing, and runs on a single AA cell, making it suitable for coastal ports, inland checkpoints, and hot industrial sites.

What apps and systems does it work with?

You can connect via USB to Polimaster’s Windows user software for configuration and data download, or via Bluetooth 4.0 to the Polismart® app on compatible iOS and Android devices for live readout, GPS mapping, and log export.

What standards and compliance does PM1703GNA-II MBT support?

It is designed to meet ANSI N42.32 and IEC 62401 PRD performance criteria, uses an ANSI N42.42-style data structure for stored history, and has been assessed against ITRAP/IAEA-style benchmarks commonly referenced by government buyers.

Compliance note: End users are responsible for confirming local regulatory approvals, licensing, calibration intervals, and export/import controls before deploying PM1703GNA-II MBT in operational or cross-border environments.
