New Hand Held Radiation Detector For First Responders

Security professionals seeking reliable radiation detection and identification for remote locations can now use a pocket-size search-and-find detector that is designed for high-sensitivity and accuracy. Because the new detector combines gamma and neutron detection, first responders and strike teams can now quickly locate a wide range of radioactive materials with a single device.

The Thermo Scientific RadEye SPRD-GN (spectroscopic personal radiation detector – gamma neutron) builds upon the family of RadEye personal radiation detectors. It is designed for use in both dynamic monitoring and isolated settings, including rural borders, on boats and on foot, that are not conducive to larger, fixed detection systems. The RadEye SPRD-GN incorporates a highly sensitive, dual sensing gamma and neutron detector. The advanced natural background rejection (NBR) technology continuously analyzes the radiation field and easily differentiates between artificial or natural radiation.

The RadEye SPRD-GN is the first handheld PRD to incorporate pulse shape discrimination (PSD), which separates real neutrons from high energy particles in the background. PSD allows the RadEye SPRD-GN to meet the strict ANSI N42.32-2006 standard for time to alarm, alarming within two seconds. Additionally, it is the first radiation detector to integrate a spectroscopic-capable CLYC (cesium lithium yttrium chloride) crystal. This technology allows for more reliable detection by measuring both neutron pulse height and shape.
