RADEAGLET is light, easy to handle and designed for high performance nuclide identification in a small, lightweight housing. It is considered the lightest radio-isotope identification device (RIID) on the market.  

In its ruggedised variant, instrument and algorithms were certified by an independent test organisation to be ANSI N42.34 compliant. Identification tests performed at US National Laboratories proved the good performance of its nuclide identification with respect to special nuclear material, especially in masking scenarios.

It measures the dose rate, locates the source and identifies it. Reliable, robust and quick. Please find further key features by scrolling down on this page.

Detector technology

RADEAGLET´s detector is small and light-weight, ready for nuclear security operations, medical isotope scanning and day-to-day work of radiation detection. It is read out with a smart signal processing technique that allows for tremendous throughput and optimal resolution. It consists of a sodium iodide NaI(Tl) crystal which is sensitive to radiation. But thats not all. RADEAGLE can be equipped with other detector materials as well. We also offer a lanthanum bromide LaBr3(Ce) variant, which provides even better resolution.

8 hours with one pack and up to 16 hours operation with extension pack

RADEAGLET features 8 hours nonstop operation, adding up to 16 hours of nonstop operation when using the extension package. Operation time is of great importance in the field. Therefore, all components of the RADEAGLET were designed for low energy consumption and efficient processing, including Automatic display dimming and energy-saving features in its computer system. 

High-Quality Bonded Display

Like in modern smartphones, the RADEAGLET display is bonded with the glass cover. The three-button keyboard smoothly integrates into the unit. Precision and accuracy where elementary design principles for the instrument. Additionally, it is easy to decontaminate.


Intuitive User Interface

The instrument has different functional modes for the user. These include: a) a Dose Rate Mode to measure the dose and count rate, b) a Detect Mode, that helps to find and locate sources, c) an Easy-ID Mode to quickly identify the source of radiation. 


Furthermore, RADEAGLET features several advanced measurement functions, including the same comprehensive spectroscopic laboratory as RADEAGLE,  e.g. with a detailed spectrum analysis screen, sensitivity adjustments for its sensors or an automatic ID with waterfall visualisation.

Wireless connectivity via removable dongle

There is a WiFi dongle positioned behind RADEAGLET´s front cover. As long as you need wireless connectivity it is safely stored. If you enter areas of high security, e.g. military perimeters or other sensitive infrastructure, often it is not allowed to actually have wireless hardware on board. Therefore, you can simply detach the dongle from the handle and the hardware is de-facto physically removed.  

Data Transfer via USB or via SD-Card

The USB port can be used for several things. You can attach a USB stick for copying your data. The RADEAGLET software has features for smart extraction of your data. It keeps you updated on the consumed memory and offers different ways of clearing the data, e.g. removing all spectra older than a month. You can also get collected data via the SD card. It can be removed and used in any common, available PC.

USB Network

You can connect to any wired network with the USB port. Just plugin a USB-Ethernet cable and you are good to go.


Spectroscopic and radiologic data measured with RADEAGLET is tagged with geographical information, once the optional GPS module is installed.

Web Interface - connect to your instrument from all your intelligent devices

Access to RADEAGLET data is very easy. After choosing your preferred way connection, either using WiFi, Hotspot, or USB, you can simply use your browser on your mobile phone, your tablet or your computer. to access the web interface of the instrument. You can view and download spectra, generate reports, make comments, review ID results and many other things.

Machine Learning Nuclide Identification

The identification of nuclides is based on the spectrum. On the computer system of RADEAGLET, a powerful mathematical algorithm identifies radioactive sources based on this spectrum. It can also find the right composition, if multiple of these sources are present. Using combinations of different machine learning methods, semantic strategies and an expert knowledge database, the algorithm is a good example about artificial intelligence powering modern sensorial equipment.


The algorithm is also fully adapted to the detector material either applying NaI specific optimisations, LaBr3 analysis with higher resolution or an advanced analysis based on the (optional, hybrid) CZT spectrum. 


The instrument and especially its nuclide identification capabilities have been demonstrated in a wide range of in-field, laboratory and acceptance tests. The ruggedised variant of RT that is using the same algorithm was certified to be compliant with the latest ANSI N42.34 standard by leading test organisations in the US. Its ability to detect and identify special nuclear material (SNM) was demonstrated by various independent tests at US National Laboratories and military facilities.


Special strength of the methods applied by RT is an extraordinary good separation of SNM like Uranium, Plutonium or Neptunium against potential masking sources from medical, industrial or naturally occurring sources. The algorithm is available as standalone Replay-Tool for Windows 8/10/11 and for macOS. It allows to compare different algorithm versions, as well, as it helps organisations in their evaluation of the result quality. 


The instrument ships with a rich set of accessories: a USB charger with international plug adapter set together with a high-quality USB cable, a car adapter for charging RADEAGLET from your car connector, a calibration box and a USB extension battery.

Always calibrated with machine learning control

RADEAGLET does not use any internal source. It does not contain any radiating material at all! Instead, we use the natural background radiation. See the tiny little peak in the spectrum? This is a peak of 40K. It is nearly always there. This is one of many peaks RADEAGLET grabs to keep the calibration in place. And because our detector is supported by quite substantial algorithmic power, it sees the tiny peak very quickly.


The software also applies machine learning techniques for storing the complicated dependencies of the peak position and the temperature.  Each individual instrument is virtually "trained" at innoRIIDs European production facilities, not only with respect to temperature values but especially to different temperature change rates (shocks).


If you require a unit with internal source, we can optionally equip the RADEAGLET with a small 137Cs source.
