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 radiation detectors save users valuable time adjudicating alarms while increasing scanning throughput. Using Natural Background Rejection (NBR) Technology, the RadEye PRD4 and PRD-ER4 radiation detectors 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. The RadEye PRD4 and PRD-ER4 Personal Radiation Detectors enable accurate dose rate measurements across the broader gamma spectrum, providing a greater assurance of personal safety. The neutron indication capability of the RadEye PRD4 provides an additional layer of detection critical to determining the level of radiation threat.
