    Description

    RadEye SPRD

    Thermo Scientific

    The Thermo Scientific RadEye SPRD is a compact and affordable spectroscopic personal radiation detector (SPRD) designed to detect, localize, and identify radioactive sources—without the complexity or bulk of traditional radiation detection equipment. Combining gamma radiation detection with nuclide identification, it brings advanced radiation analysis to front-line personnel in a pager-sized package.

    Ideal for law enforcement, border security, emergency response, and hazmat teams, the RadEye SPRD balances performance and practicality with its lightweight form factor, long battery life, and intuitive interface. Users can easily wear it on a belt or carry it in a pocket during routine patrols or large-scale events.

    A key feature is its Natural Background Rejection (NBR) technology, which allows users to differentiate between naturally occurring radiation and potential man-made threats. This patented system enhances sensitivity and selectivity during “search and find” operations, minimizing false alarms and improving reaction time. When a significant radiation source is detected, the device can be quickly switched to nuclide identification mode for real-time analysis. It identifies isotopes commonly associated with nuclear weapons, improvised nuclear devices (INDs), or radiological dispersal devices (RDDs)—making it a powerful tool in both routine and high-threat environments.

    Features

    • Faster detection of radiation at greater distances without increasing false alarms

    • Faster distinction between potential threats to public safety and non-threat sources (medical or natural)

    • Vibration alarm mode for covert operation

    • Raised Buttons with positive response for gloved hand operation

    • Intuitive interface with easy to read results

    • Minimum attention required for operation

    Operational Flexibility

    Enable users to make informed decisions at the scene that improve adjudication times, lower the number of nuisance alarms, increase reachback data quality, and reduce the time allocated to non-threat events.

    • Combines detection and identification technologies in a single instrument

    • Detects, identifies, and categorizes Artificial or Natural sources of radiation, i.e., Natural, Medical, or Investigatives

    • Sensitive CsI detectors are configurable to specific needs or CONOPS

    Configurability

    Easy-to-use tools for configuration and setup for any size operation. These tools improve consistency, simplify user training, and improve flexibility across multiple agencies and departmentss

    • Radeye.exe software simplifies the configuration and setup of new PRDs

    • Predefined parameters can be stored in a configuration file and written to PRDs to support different CONOPs and deployments

    Reducing Nuisance Alarms

    RadEye PRDs are equipped with Natural Background Rejection (NBR), a proprietary technology used to eliminate fluctuating natural background levels while measuring radiation.

    • Distinguishes artificial radiation from naturally occurring radioactive material (NORM)

    • Reduces the number of false alarms by 80% without the need to increase alarm thresholds thresholds

    • Detects low levels of artificial radiation such as hidden or shielded sources

    • Alarms when energy imbalances are detected even if the total radiation level does not elevate
