Aurion reports all exposure results in increments of 5 mrem or .05 mSv. Dosimeters are
activated, deactivated and read out on the display unit. At the time of read out, an exposure
record is logged into memory on both the dosimeter and the display unit.
An Aurion dosimeter must be activated (Chapter 7, p. 14) before use to enable the exposure
results to be reported to the current user (participant).
Obtain additional information about the dosimeter by placing the unassigned dosimeter with
no smart card inserted face down on the display unit in the read out area (display unit must be
configured). The following information appears on the display unit screen:
Review the available dose and other dosimeter information after data transfer at Landauer’s
web site at the Equipment – Dosimeter Detail link on Aurion’s sidebar menu (Chapter 9, p.
21).

When an integrated dose exceeds 5 rem, an emergency read out by Landauer may be required.
