RadEye PRD4 and PRD-ER4 Personal Radiation Detector

Thermo Scientific™ RadEye™ PRD4 and Thermo Scientific™ RadEye™ PRD-ER4 Personal Radiation Detectors help security, emergency response, and radiation safety teams screen people, vehicles, facilities, and materials with high sensitivity, fewer nuisance alarms, and greater confidence in the field. The RadEye PRD4 detector is used for basic screening and interdiction, whereas the RadEye PRD-ER4 detector extends PRD-style screening to higher dose-rate operation capability. Built with natural background rejection (NBR) technology, both the RadEye PRD4 and RadEye PRD-ER4 detectors help distinguish artificial radiation from naturally occurring radioactive material (NORM), thereby reducing time spent adjudicating alarms and improving screening throughput. For missions requiring an added layer of threat awareness, the RadEye PRD4 detector also provides neutron indication capability.

A wide dose-rate measurement range helps users maintain awareness from routine screening through higher-dose-rate scenarios, such as locating orphan sources, responding to radiological incidents, investigating suspect packages or vehicles, and supporting nuclear facility security operations. This is important because it allows teams to continue assessing changing conditions with a single personal detector. This supports safer approach decisions, faster triage, and better protection of personnel.

Detect radiation more confidently in real-world environments

• High sensitivity

  Detect shielded radiation sources sooner to support security screening, patrol, source search, and emergency response.

• Neutron indication capability

  The RadEye PRD4 detector provides neutron indication capability as an added layer of threat awareness especially relevant for border security, source search, interdiction missions, and nuclear incident response.

Move faster from alarm to action

• Automatically distinguish artificial radiation from natural background

  The NBR feature reduces false alarms even amongst the most challenging environmental conditions by automatically distinguishing natural vs. artificial radiation, helping to guide the user’s response and choice of escalation level.

• Comprehensive data neatly organized and presented on screen

  Dose-rate data, alarm status, and identification information are organized for quick interpretation and confident field decisions.

• Large display

  A large, easy-to-read screen helps users quickly view critical information while moving, wearing gloves, or operating under pressure.

Designed for users who do not use radiation detectors every day

• No retraining or relearning for infrequent users

  An intuitive design helps occasional users, rotating personnel, and multi-agency teams operate the detector with confidence.

• Simple 4-button design

  Streamlined controls reduce complexity and make essential functions easy to access in the field.

• Small and lightweight

  Compact design supports comfortable, continuous wear during long shifts, patrols, inspections, and response operations.

Rugged enough for demanding field conditions

• Drop-resistant to 1.5 m

  The detector is built to withstand everyday handling in patrol, checkpoint, industrial, and emergency response environments.

• IP65 rated

  Housing helps protect against dust and water exposure for reliable use in outdoor, facility, port, and field applications.

• Operates in extreme temperatures

  Sturdy design supports radiation awareness in hot, cold, and challenging operating environments.
