The RadSeeker was specifically designed to meet US Department of Homeland Security (DHS) requirements for a system capable of detecting and identifying nuclear-threat materials.

It uses technology that couples advanced spectrum-processing and identification algorithms with a choice of highly sensitive detectors – resulting in superior identification accuracy.

This sophisticated detector system is capable of resolving complex masking scenarios and exceeds all ANSI N42.34 (2006) requirements for the identification of bare, shielded and multiple isotopes.

The RadSeeker is easy to use while supplying the operator with quick, simple, specific information for threat assessment.

It can be used during searches to detect radioactive sources and identify whether the radioactive material uncovered is harmless or dangerous. For each source identified, the RadSeeker provides a risk assessment describing the source as innocent or a threat, removing all the guesswork from the operator.

In emergency situations, radiological response teams can quickly and accurately determine whether a source is present and the level of threat it represents.

Built-in wireless capabilities, which include both WiFi 802.11 and a satellite-phone interface, provide those in a remote command centre with easy access to information such as the threat identified, source spectra and the location of the device/operator.

In a situation that is deemed unsafe to send a responder, the RadSeeker can be placed mechanically while monitoring and controlling the device from a safe distance.
