1. Introduction
The AccuRad PRD is a Personal Radiation Detector (PRD), packaged in a small, rugged
and easy to use form factor. The AccuRad PRD is a high-performance measurement
device for operations requiring detection, search and localization of radiation sources.
AccuRad addresses all applications requiring efficient detection of radiological threats in
civilian defense.
The AccuRad PRD combines one sensitive low range detector to quickly detect low
gamma radioactivity levels and one high range detector for extended dose rate range and
dose measurements.
The AccuRad PRD is a self-operating device that automatically detects gamma radioactive
sources. A unique “on the move” localization algorithm enables intuitive source search by
directional screen indicator.
When a source is detected, the AccuRad PRD triggers various sound and visual alarms
and/or vibrations. The device has a built-in discreet mode that mutes alarm sound, thus
making it convenient to use in crowded environments (airport, malls, metro stations,
stadiums, streets, etc.).
The AccuRad PRD is compact sized for performing one-handed measurements, event
when wearing gloves. The user-friendly interface utilizes two display screens; one large
front case display; a smaller top display, and five buttons. The integrated belt clip affixes
securely to a belt or pocket, allowing easy view of the top display without removing.
The AccuRad PRD is powered by two AA batteries (1.2V to 1.5V).
The AccuRad PRD is designed for pairing to a smartphone with the AccuRad App. The
AccuRad App provides sharing features including data logging, batch processing,
messaging (email, SMS), and reachback connectivity to common operational data
platforms.
Optionally, the AccuRad PRD can also be remotely monitored by the SpirVIEW
Supervision software or RadResponder for situational awareness along with the other
SPIR family instruments.
The AccuRad PRD complies with the relevant current international standards (IEC, IAEA,
ANSI).
