RADEye SPRD-ER
Personal Radiation Detector
The RadEye SPRD-ER radiation detector identifies and categorizes specific types of radiation or radioactive material, and can be configured to support your missions or user skills.
By providing significant detector sensitivity for search and find, combined with accurate high dose rate radiation measurement, the RadEye SPRD-ER is a suitable instrument for all users and may be the only radiation detector you need.Agencies have seen nuisance alarms reduced by 80% as a result of concentrated NORM materials such as granite, natural stone and subway tiles after deploying instruments that utilize our Natural Background Rejection (NBR) Technology. The patented Natural Background Rejection algorithm (NBR), allows the RadEye SPRD-ER to immediately separate man-made (non-NORM) gamma radiation from natural background fluctuations in real-time during operation. When enabled, the RadEye SPRDER automatically classifies and identifies gamma radiation as a result of an NBR alarm.

Simple 4 button design
Large display with improved screen resolution and brightness
Quickly guides you through next steps after an alarm
Comprehensive data neatly organized and presented on screen
Get results automatically, without the need to press buttons
No retraining or relearning for infrequent users
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
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
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
