Best-in-class ID: Real-world usability

The hardware and software enclosed in its ruggedized plastic case is designed to simplify a complicated radiological picture. Multifarious alarms at several levels and in varying modes—audible, visible, vibratory, earphone—warn the user of the presence of radioactive sources. In addition to gamma counts per second, neutron counts per minute and radiation dose rate in micro- or milli-Sv, the organic LED screen displays the isotopes present, and, crucially, which ones are natural background and which ones are threats.

Connectivity including IEEE 802.11b/g/n wi-fi, ethernet and satellite phone connection via RF modem enables the transmission of detection information. Detections are time-stamped with location determined by latitude and longitude using global positioning satellites.

There is a choice of two enhanced gamma spectrometers; NaI (RadSeeker CS) and LaBr3 (RadSeeker CL). Both detect emissions in the 25 keV-3 MeV range and identify isotopes using Discovery Technology’s advanced algorithms with a customizable library of 41 nuclides. Due to the higher intrinsic resolution the RadSeeker CL is the ultimate in this class of instrument against masked, shielded and mixed sources. However, the comprehensive development program has ensured that the RadSeeker CS demonstrates superior performance even when compared to competitive LaBr3 RIDS under government tendering. This is achieved through developments in signal processing (deconvolution) and energy stabilization and provides for ID performance previously not seen in this class of radiation identifier regardless of the model choice.
