The RadEye SPRD is an economic and easy to use Gamma radiation detector that enables it’s user to detect, locate and identify radioactive sources. The capability to perform nuclide identification is added to the advantages of a pager sized personal radiation detector like compact size, low weight and long battery life time.

This combination makes the RadEye SPRD detector a perfect tool for those users where the detecting, locating and identifying sources of radiation is  a minor requirement of their main task.



Spectroscopic Personal Radiation Detector

the RadEye SPRD offers as well the patented Natural Background Rejection (NBR) technology that provides high sensitivity with immediate high selectivity to differentiate between natural and man-made radiation during search and find operation of the device. Once an alarm indicates the presence of a significant radiation contribution, the RadEye SPRD can be put into nuclide identification mode and the source of radiation can be analyzed.

The detection and analysis of hidden radioactive nuclides require a radiation identification tool with high sensitivity and accuracy. Detect, localize and identify radiation sources generated by manmade devices such as nuclear weapons, improvised nuclear devices (INDs) or radiological dispersal devices (RDDs) with the pager-sized Thermo Scientific RadEye SPRD Spectroscopic Personal Radiation Detector.

The RadEye SPRD detector provides emergency services and law enforcement teams like border guards or special forces with high-performance detection and nuclide analysis for any scenario.

  • 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


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

  • 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
