Accurad PRD
Personal Radiation Detector
A discreet yet robust PRD designed for law enforcement, fire rescue, and other emergency responders to detect and interdict nuclear and radioactive materials. It also provides dose measurement and alarming capabilities for event response.
The AccuRad PRD is the first PRD developed in close collaboration with state and federal law enforcement and first responders to fit seamlessly into their routines and address the most critical, in-the-field needs from a radiation detection device.
The AccuRad PRD runs on innovative Variable Background Suppression (VBS), allowing operation in varying background environments and will alarm only for a real threat or hazard. The AccuRad PRD provides dose measurement and dose alarms for radiological events, utilizing Mirion’s long-standing expertise in the radiation safety industry.
Solid and durable, with an impact-resistant covering
Simple to use − no training required
Discreet, with a top-screen display for quick-glance reading
Directionality, helping users zero in on trouble faster
Low cost of ownership
For discreet, hands-free detection
The AccuRad PRD is lowprofile and easy to read with the top-screen display. Users no longer need to remove the PRD to take a look.
For waterproof protection
for when teams are (literally) putting out fires.
For the reality field of work
rough treatment, harsh conditions. The AccuRad PRD is solid, durable, with an impact-resistant covering to stand up to the test, time and time again.
For an entire week, month, mission
without a battery change. The AA batteries in the AccuRad PRD last for 900 hours in the field, and are easily replaceable with commercial batteries.
For "set it and forget it" use
with minimal training and maintenance required. The AccuRad PRD is in-the-field easy — simple to use even in the toughest situations and offers a tutorial library in the smartphone app.
