1Overview
The PM1703, the PM1703GNA, and now the PM1703GNA-II MBT mark successive generations of gamma and gamma-neutron pagers built for the homeland security market. The device keeps the rugged, simple interface the field expects, then pairs it with the analytical ability and processing power of a far larger instrument. It operates much like a conventional radiation detection pager, but it also collects and stores spectroscopic data. That added capability turns a personal alarm into a tool for managing and expertly analyzing radiological incidents.
Alarm data downloads from the pager to a Pocket PC, IPAQ, or smartphone for further analysis, isotope identification, or electronic forwarding to back-end support. A team leader can hand staff a detector that alarms sensitively in real time and still stores and transfers what it found. Data transfer is simple. It ties into existing network infrastructure, GPS functionality, or a classified AI protocol without disrupting how the team already works.
2Key Features
- Highly sensitive CsI(Tl) and LiI(Eu) scintillation detection for low-level gamma alarming.
- Simple two-button operation that requires no specialist training to run in the field.
- USB, Bluetooth, and IRDA communication for flexible data download and transfer.
- Shockproof hermetic case rated for rough handling and outdoor use.
- Designed for low EMI susceptibility around portable radios, cell phones, and similar equipment.
- Stores spectroscopic data on alarm, enabling later isotope identification and reachback.
3Detector & Performance
Gamma detection uses a CsI(Tl) scintillator read out by a silicon photomultiplier (SiPM), backed by a GM counter for higher dose rates. Neutron detection uses a LiF/ZnS assembly. The product features also describe the detection chemistry as highly sensitive CsI(Tl) and LiI(Eu) scintillation, well matched to the low count rates seen in early-warning screening.
The combination matters in the field. The scintillator delivers the sensitivity needed to catch weak or shielded sources during a walk-by, the GM tube extends the usable dose rate range, and the LiF/ZnS layer adds neutron sensitivity for special nuclear material that a gamma-only pager can miss. Detailed sensitivity, dose rate, and energy figures are not published on the product page and are flagged for verification in Section 4.
