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 (AccuRad for short) 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 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 is a self-operating device that automatically detects radioactive and nuclear
sources. A unique “on the move” localization algorithm enables intuitive source search by
directional screen indicator
When a source is detected, the AccuRad triggers various audible, visual alarms and/or
vibration alarms. It has a built-in discreet mode for silencing alarm sounds, thus making it
convenient to use in crowded environments (airports, malls, metro stations, stadiums, streets,
etc.).
The AccuRad is compact-sized for performing one-handed measurements, even 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 is powered by two commercially available AA batteries (1.2V to 1.5V).
The AccuRad 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.
AccuRad complies with the relevant current international standards (IEC, IAEA, ANSI).
Optionally, the AccuRad can also be remotely monitored by the SpirVIEW Supervision
software or RadResponder for situational awareness along with the other SPIR family
instruments.
