Handheld Radiation Search and Identification Device

One tool for dose, ID, and contamination in the field

The PM1401K-3M is a compact, all-in-one radiation monitor and radionuclide identifier for Australian border teams, EOD/CBRNe units, industrial safety crews, and first responders. It combines gamma dose-rate survey, alpha/beta contamination checks, gamma spectrometry, and ^137Cs activity measurement in one IP65-rated package.

Modular hardware (sample fixtures, α/β accessories, telescopic pole) and a desktop companion app support an end-to-end workflow from first detection through isotope ID, logging, mapping, and reporting.

Why Teams Choose PM1401K-3M?

Faster identification: 1024-channel CsI(Tl) spectrometer with ≤9% resolution at ^137Cs for rapid, confident gamma ID in the field.

Mission-ready ruggedness: IP65, shock-resistant housing, –20 to 50 °C operating range, and belt-mount form factor for all-weather deployments.

Unified UX: One device covers dose-rate, search, ID, α/β flux, and ^137Cs activity with consistent menus, colour LCD, and simple mode switching.

Long endurance, simple power: Runs on 2×AA cells for ≈300 h in background conditions, keeping logistics, training, and spares straightforward.

Trusted libraries & data: ANSI N42.34-style radionuclide categorisation (IND/MED/NORM/SNM), GPS tagging, USB export, and Polimaster desktop software for audit-ready records.

Frequently Asked Questions

What radiation modalities does the PM1401K-3M support?

It measures gamma dose rate and spectra, detects alpha, beta, and gamma sources, measures α/β flux density, and supports ^137Cs activity measurements in food or soil samples.

How rugged is the instrument for field use?

The PM1401K-3M is IP65-rated, shock-resistant, and specified from –20 °C to 50 °C with high humidity, making it suitable for most Australian climate zones and first responder scenarios.

Does it integrate with our existing devices and workflows?

Yes. Data and spectra are offloaded via USB to Polimaster’s desktop companion software, where you can review events, apply your radionuclide libraries, and export reports into existing evidence and GIS systems.

What standards and libraries does it align with?

The PM1401K-3 family is designed to meet ANSI N42.33, ANSI N42.34, IEC 62327, and ANSI N42.42, with radionuclide libraries structured for IND, MED, NORM, and SNM categorisation. Always confirm local approvals with your regulator.

What exactly is included in the kit?

A standard delivery typically includes the instrument, carry case, belt clip, α/β accessories, USB cable, batteries, and software, but contents can vary by tender and distributor; request a detailed packing list with your quote.

Compliance note: Specifications, libraries, and standard references are subject to change by the manufacturer. Local approvals, licensing, and export controls for radiation detection equipment remain the responsibility of the purchasing organisation.
