INTRODUCTION

3
The AccuRad™ PRD is a Personal
Radiation Detector (PRD) designed
for law enforcement, fire and rescue,
and other emergency responders
to detect and interdict nuclear and
radioactive materials. It also provides
dose measurement and alarming
capabilities for event response.

4
Exceptional Radiological Performance
The AccuRad PRD features accurate and wide dose
rate measurement from background to 1000 Rem/h;
mitigation of false alarms with Varying Background
Suppression (VBS). Cumulative dose measurements
are in compliance with industry dosimetry standards.
Smooth User Experience
Dual display screens and large buttons optimize
operation for belt-worn or handheld applications;
the AccuRad PRD quickly alerts the operator when
a threat is detected through eective loud audible,
attentive vibration, clear visual display and bright LED
alarm indicators; one-touch alarm acknowledgment;
automatic data recording.
Radar Indication Leading Straight
to the Source
An intuitive radar screen provides directional indica-
tion to help localize a thread in a wide or crowded
environment.
Discreet Mode for Covert Operations
Discreet mode silences alarms for stealth applica-
tions. USB-C headphone connectivity and silent
vibrations add a greater level of stealth operation.

5
Robust Protection
The AccuRad PRD is resistant to dust, sand and
moisture, drop tested at 1.5 m, and rated IP-67.
The PRD body has superior protection providing
shock resistance and easy handling. The AccuRad
PRD can be used in temperatures from -4 °F (-20 °C)
to 140 °F (60 °C).
>900 Hours Continuous Operation
The AccuRad PRD has outstanding battery life and is
powered by two commercially available AA batteries.
Simplified Data Transmission via
Near Field Communication (NFC) and
Bluetooth Low Energy (BLE)
Smartphone application (Android, iOS) enables
reachback, remote display and alarms,
personalization of AccuRad PRDs by batch.

USING THE ACCURAD PRD
Top Display
Using the PRD in Discreet Mode
The Discreet mode can be used when the operator does not want the PRD alarms
to be visible to others. By default, the audible and visual alarms (LEDs) in Discreet
mode are deactivated while the vibration and display messages are active.
Wearing the PRD
The reference direction of the measurement is orthogonal to the front display
to guarantee an optimal measurement of both detectors when the AccuRad
PRD is carried. The reference direction of the measurement and the distance
measurement have an impact of the quality measurement.
