RADEAGLET-Ruggedized (RTR)

Overview

RADEAGLET Ruggedized, in short the RTR, is a robust and ruggedized handheld radiation detection instrument. It is certified against the ANSI N42.34 standard by independent US National Laboratories. RTR specifically addresses the challenges of in-field missions and contributes to combatting nuclear terrorism.

Detector technology

NaI(Tl), LaBr3(Ce, Sr), or CZT+NaI(Tl) can be used as detector materials. The latter combination is a hybrid combination of a high-resolution detector and a medium resolution material, in order to achieve good sensitivity while having highest resolution at the same time. Moreover, RTR can be used as host for extension probes for detecting Alpha/Beta radiation or X-Rays. A high-resolution CZT detector can also be provided as extension probe.

Modern, easy-to-use user interface

The user interface of the RTR was designed based on decades of experience in handheld radiation instrumentation. It features modes of operation that are unique in the field and is recommended by experts and users. On field missions, you want an user interface that is on point, helping you to fulfil your objectives: Find increased levels of radiation, determine the strength of the radiation in terms of dose rate and identify the sources.

Easy mode for identification

RADEAGLET-Ruggedized features the same Easy-ID mode like RADEAGLE and RADEAGLET-Standard. It visually guides you to find the optimum distance to source for performing a good ID. Of course, RTR also keep you or direct you towards a safe distance, in case the source is very strong.

Long-Lasting Battery Power

A smart lithium power unit with digital lifetime processing provides runtimes of more than 14 hours (without external probes). Users can check visually the battery status via the inbuilt indicator display. The battery can be hot-swapped. An internal battery will power the instrument while changing the main battery.

Magnetic USB Data Transfer Connector

The USB communication cable is connected to the instrument via a magnetic interface. This is part of the ruggedisation concept and prevents accidental drops of the instrument if the cable is pulled.

USB Connector for External Probes

A series of additional probes are available for the RTR. Alpha/Beta detectors can be found in a dedicated page.

Secure, Detachable Carrying Strap

A carrying scrap can be easily attached and detached. It secures the instrument against accidental drops.

Rugged Carrying Case and Accessories

The RTR is shipped in a rugged carrying case that keeps the instrument safe during transport. It contains all accessories that are provided with the instrument, including charger, car charger, a USB drive, the calibration source and connection cables.

GPS Positioning

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

Autocalibration

The RTR does not use any internal source. It does not contain any radiating material. 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 the RTR grabs to keep the calibration in place. And because our detector is supported by quite algorithmic techniques, it sees the tiny peak very quickly. The software also applies machine learning techniques for storing the complicated dependencies of the peak position and temperature. Each individual instrument is virtually "trained" at innoRIIDs production facilities, not only with respect to temperature values but especially to different temperature change rates (shocks). Should you still require a unit with internal source, we can optionally equip the RADEAGLET with a small ¹³⁷Cs source.

Nuclide identification powered by artificial intelligence

The identification of nuclides is based on the spectrum. On the computer system of RADEAGLET-R, 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. RTR 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 RTR 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.
