Description
Thermo Scientific
The Thermo Scientific RadEye PRD4 is a next-generation personal radiation detector (PRD) built for high-throughput scanning and fast decision-making in the field. Designed for use by first responders, law enforcement, and nuclear security teams, the PRD4 combines exceptional sensitivity with advanced background rejection—allowing professionals to act with confidence while minimizing false positives.
At the core of the PRD4 is Natural Background Rejection (NBR) Technology, which filters out fluctuations in naturally occurring radioactive material (NORM), letting users focus only on credible threats. Its neutron indication capability adds a critical detection layer for identifying special nuclear material (SNM), improving overall situational awareness in high-risk environments.
Compact and easy to use, the RadEye PRD4 also supports configurable alarm thresholds and user modes, making it adaptable for teams of varying experience levels.
