Personal Radiation Detector
Achieve highly sensitive radiation detection with few nuisance alarms with Thermo Scientific RadEye PRD4 and PRD-ER4 Personal Radiation Detectors. RadEye PRD4 and PRD-ER4 save users valuable time adjudicating alarms while increasing scanning throughput. Using Natural Background Rejection (NBR) Technology, the RadEye PRD4 and PRD-ER4 ignore fluctuations in naturally occurring radiation (NORM) while analyzing the energy imbalance of artificial radiation. Additionally, these radiation detectors identify the discovered material in a manner configurable for your operation or user skills.

Neutron alert
The neutron capability of the RadEye PRD4 personal radiation detector provides an additional layer of detection capability that is critical in determining the level of the radiation threat or problem.
Personalized for each user
Configure the RadEye PRD4 personal radiation detector as a simple 0 to 9 radiation level gauge Or turn on dose rate readings, simplified gamma Natural and Artificial classification, or basic count rate mode.
Stay Focused
With advanced NBR, agencies have seen nuisance alarms due to granite, natural stone and subway tiles reduced by 80% after deploying the RadEye PRD4 without increasing alarm thresholds or sacrificing sensitivity.
In-Field Calibration
The ability to calibrate the units in the field saves on down time and extra inventory to support costly turn-in/replacement resources.
