Chapter 1: Introduction
Aurion System
Landauer’s Aurion System focuses on operational monitoring where the radiation safety
professional or worker needs prompt and reliable radiation dose information locally. The
intent of this dosimeter is not dose of record. The Aurion system consists of the Aurion
dosimeter and display unit/reader, smart card identification technology and web-based data
management programs. Aurion includes semiannual recalibration services and calibration
certification of each dosimeter.
Aurion is a lightweight, rugged dosimeter that can be worn in a variety of work environments
and read out as many times as needed. Readings are logged by date and time into memory
residing on both the dosimeter and reader. The battery-less dosimeter provides the dose
information to the reader through radio frequency technology making for easy, foolproof
operation. The display unit shows both the total integrated dose since activated by a given
user as well as the incremental dose monitored since the last readout.
Smart card technology provides the means to personalize each dosimeter as well as
electronically identify the user to the dosimeter and reader for a secure chain of custody. The
smart card permits multiple people to use any Aurion dosimeter without the administrative
burden of keeping issuance logs. The service is ideal for short-term monitoring of visitors or
staff that infrequently enter a radiation controlled area.
All readout data can be uploaded through the Internet into Landauer’s web site and Aurion
database where reports and queries enable the radiation safety professional to view the
information from various perspectives such as by user, time, dose threshold or dosimeter.
Data can also be exported from the Aurion database into a Microsoft

 Word or Adobe

 PDF file, or as a text file where it can be imported into local spreadsheet or
database software.
General Operation
Your initial shipment for Aurion service contains dosimeters, smart cards for insertion into
the dosimeters to identify the user, and a display unit(s) accompanied by a charger with a
cable that connects the display unit to your personal computer.
Before using Aurion for the first time, charge and configure the display unit and complete a
performance check on each dosimeter. After a dosimeter has passed its performance check,
insert a smart card into the dosimeter and activate the dosimeter on the display unit. The
dosimeter is now ready to wear. After use, read out the dosimeter on the display unit that
records and displays your current dose.
You establish the intervals for reading dosimeters and transferring data from the display unit
through your personal computer and the Internet to the Aurion database at Landauer’s web
site. You manage the reporting results at the Aurion web site by choosing the criteria of
reports to view, print or export to your personal computer to perform onsite analysis.
