Chronic & Acute Charts
The subsequent tabs are charts for the Acute and Chronic windows for both Alpha data. You
can follow the same instructions as above to refresh the template with new data from your unit.
For additional isotopes-of-interest, create copies of the tabs. These points are supplemental and
may help with instruction:

Because there are several data tabs, you can either select Refresh All from the first data
tab and choose the files one after the other in order , or select Refresh from each tab and
choose one file at a time.


When formatting the Y-axis , the whole chart does not need to be in view, as the
minimum detectable line will likely be too high in the beginning to achieve good
readability of the rest. The chart is best read when the typical readings are within the
bottom fifth of the chart. See the example chart below for typical appearance. Once
formatted, leave the axis set for better comparisons between data files.

The X-axis may also need to be formatted for different dose measurement lengths. The
length in time is automatic but the major unit needs to be fixed. For 1 hour increments
use 0.04166666, for 2 hours use 0.08333333, for 4 hours use 0.16666666, and for 8 hours
use 0.33333333.
