 Reference Guide

Landauer irradiates each dosimeter shipped with a known dose to check its performance
before use. To check a new dosimeter before use for the first time, place dosimeter without a
smart card inserted face down on the display unit in the read out area. The Performance
Check screen indicates a “PASS” or “FAIL.”  A dosimeter is permanently disabled for use if
it fails the performance check.

If the dosimeter fails its check:

Seconds later:

If a smart card is inserted into the dosimeter for activation before completing the
performance check, the performance check is automatically completed in the background. If
the dosimeter passes, it is activated for use. If the dosimeter fails, Screens 7.3 and 7.4
display.

Activate each dosimeter before use to make it possible to report a dose to the current user
(participant). To activate a dosimeter, insert a smart card into a dosimeter to electronically
identify the participant and place the dosimeter face down on the display unit in the read out
area until Screen 7.5 displays.

After the dosimeter is read out, all doses are reported to the participant assigned to that smart
card. Each readout is date and time stamped within the display unit’s memory. After data
transfer, exposure records can be viewed at Landauer’s web site at the Dose Reports link on
Aurion’s sidebar menu (Chapter 9, p. 19).
