High-resolution spectroscopic radiation detector

With the highest detector resolution available in a pager-sized device, the identiFINDER R300 spectroscopic radiation detector virtually eliminates the false alarms and false positives that are so common to personal radiation detectors. With both detection and identification capabilities available in a single, rugged device, those on the front lines of homeland security can trust the nanoRaider to make their job easier.

About the same size as a mobile phone, the belt wearable R300 provides continuous detection capability with visible, audible and tactile alerts. Once radiation has been detected, the fast identification capability of the instrument provides essential information to the user in the field, enabling them to make a next step determination. The One Touch Reachback™ feature integrated into the R300 allows the user to immediately send a notification to team members, superior officers, situation management personnel, and expert analysts – all with a single push of a button.

The R300 spectroscopic radiation detector uses uniquely constructed Cadmium Zinc Telluride (CZT) detectors that enable exceptional sensitivity and identification capabilities never before seen in a spectroscopic personal radiation detector (SPRD). The characteristic design of FLIR CZT detectors is more rugged than scintillation-based detectors and does not require temperature stabilization. The nanoRaider is also available with an optional neutron detector as well as a full range of accessories.

To reduce the training burden, the R300 uses the same easy to understand and navigate user interface common to the entire family of FLIR radiation detectors. With two-button controls, operators can pick up a R300 and begin using it simply and quickly.

  • Virtually eliminates the false alarms and false positives inherent in other personal radiation detectors.
  • No consumables and maintenance intervals of 5 years.
  • Configuration and data download through a standard web browser. No need for a dedicated PC software.

The most advanced communications in a spectroscopic radiation detector 

Like other FLIR radiation instruments, the R300 spectroscopic radiation detector enables the most advanced communications features available in any class of radiation detector. With One Touch Reachback, users can immediately provide full spectroscopic data as well as detailed device information, time, and GPS location to as many people as necessary with the push of a button.

No longer do users have to physically connect their device to a computer, install secondary software, or use external email to provide alarm notifications. Through a simple Bluetooth® connection, such notifications are all but automatic. This unique capability provides added security by retaining all detection and identification data on the instrument itself and not on a local computer.

Cadmium Zinc Telluride radiation detector

Cadmium Zinc Telluride (CZT) detectors are known for better resolution in a smaller detector without the need for temperature stabilization. Through ongoing research and development, FLIR has optimized this material for radiation detection and accurate source identification. In the R300, this ability virtually eliminates the inconvenience and expense associated with false alarms and false positives, not to mention the time involved in obtaining secondary inspections necessary to clear an alarm. In addition, the CZT material is naturally more rugged than typical scintillation detectors and is able to survive the general abuse typical of field deployments.

A spectroscopic radiation detector suitable for you

Unlike other companies, FLIR takes the approach that one size doesn’t fit all. We understand how important it is to have an instrument that meets the specific requirements of the mission at hand. To that end, the nanoRaider provides the same high-quality results as much larger instruments, but with an inconspicuous, compact design.

The entire family of FLIR radiation instruments has been developed to address the specific sensitivity, resolution, size, and weight requirements of a variety of applications. Furthermore, each of these instruments, including the R300, employs the same simple to use and understand interface, which in turn reduces the training burden. With more than 14,000 radiation instruments deployed worldwide, the well-known and trusted FLIR user interface has become industry standard.

R300 neutron detection

Helium-3 neutron counters are detectors that are sensitive to thermal (slow) neutrons. As an option, in addition to the specific gamma radiation detector material used, identiFINDER R300 can also be equipped with He-3 counters to measure thermal neutrons.
