FLIR identiFINDER R225
Spectroscopic Personal Radiation Detector
Teledyne FLIR describes the identiFINDER® R225 as a rugged, pager-sized Spectroscopic Personal Radiation Detector (SPRD): a personal radiation detector you wear on the belt that also identifies gamma sources, run with the familiar three-button control common to all identiFINDER products.

≤0.89 lb(406 g)
≥24hInternal Li-ion battery
Fast front-line detection and response
Worn on the belt. Identifies on the spot.
Teledyne FLIR built key features of the R225 on feedback from its predecessor, the identiFINDER R200, including operating in multiple languages. The screen is brighter and in colour, and the holster leaves it completely visible.
Alarm to identification
Two instruments’ work, one belt-worn unit
The R225 is rated to two standards at once: ANSI N42.32 for personal radiation detectors, and ANSI N42.48 for spectroscopic PRDs, including nuclide identification. In practice that is one workflow, from the belt to a named isotope to remote viewing and ANSI N42.42 data output.

Alert you can see and hear
Alerts come through a sunlight readable color display, LED alarm indicators and an audible alarm. The colour screen is visible in sunlight and through polarized sunglasses.

Name the isotope
Identification uses the field-proven template matching algorithms found across the entire identiFINDER family, with the R225’s spectroscopic detector behind them.

Wearable form factor
Pager-sized, made to be worn
A personal detector does its job only when it is on you. The R225 is pager-sized and weighs ≤0.89 lb (406 g), with a ≥24h internal battery and a replaceable CR-123A back-up.

Detector options
One body, two crystals
Every R225 uses a single (18mm)3 cubic crystal read by a silicon photomultiplier (SiPM). The choice is the crystal: cesium iodide for sensitivity, or lanthanum bromide for sharper peaks.
G & GN models
CsI(Tl)
(18mm)^3 Cesium Iodide (CsI) with Silicon Photomultiplier (SiPM). Teledyne FLIR cites exceptional sensitivity and identification capability.
- Typical resolution
- ≤7.5 %
- FWHM at 662 keV
- Gamma sensitivity (Cs-137)
- 2.1 cps/µrem/h
LG & LGN models
LaBr3(Ce)
(18mm)^3 Lanthanum Bromide (LaBr3(Ce)) with Silicon Photomultiplier (SiPM), the higher-resolution option.
- Typical resolution
- ≤4 %
- FWHM at 662 keV
- Gamma sensitivity (Cs-137)
- 1.94 cps/µrem/h
What resolution means
Smaller number, narrower peak
Typical resolution is quoted as the width of a gamma peak at half its maximum height (FWHM), here at the 662 keV line. The smaller the percentage, the narrower the peak the detector draws.

Rugged & connected
Survives the mission, reports in real time
Teledyne FLIR’s two other promises for the R225: wear it with confidence in the harshest environments, and get critical information off it in real time.
Wear with confidence

FAQ
Questions we get asked
What is the difference between a PRD and an SPRD?
The R225 is both ANSI N42.32 PRD standard fully compliant and ANSI N42.48 SPRD standard fully compliant, including nuclide identification. The spectroscopic detector lets the same belt-worn unit identify the gamma source, not only measure dose rate.
What are the G, GN, LG and LGN models?
There are four configurations. G & GN models use an (18mm)^3 CsI(Tl) crystal (≤7.5 % FWHM at 662 keV); LG & LGN models use an (18mm)^3 LaBr3(Ce) crystal (≤4 % FWHM at 662 keV). The ZnS neutron detector is on GN & LGN models only. Request a quote and tell us which configuration you need.
How long does the battery last?
Internal single cell Li-ion operational battery life ≥24h; replaceable back-up CR-123A operational battery life ≥12h. Teledyne FLIR describes the back-ups as hot-swappable. Wall and car adapters and a USB cable are supplied.
Does it need user calibration?
Teledyne FLIR lists automatic calibration, stabilization, and no user maintenance required, with sourceless gain stabilization. For repair or other service, see the FarrWest Repair Depot.
Can it be decontaminated?
The R225 is IP67 rated for use in harsh environments or temporary submersion during decontamination (protection rating IP67 according to IEC 60529).
How long does it take to train an operator?
Training requirements are <10 mins for operator; 1 day for advanced user. The R225 uses the three-button control common to all identiFINDER products.
Can supervisors see readings remotely?
Yes. The mobile app (iOS & Android) can monitor and control the unit remotely, the device has on-board webserver software, and built in communications and a robust API enable integration with user deployed networks. Communication is USB-C, WiFi and Bluetooth (BLE 5.0).
