Variable Definition
A_ACT
Alpha Activity expressed in units of activity per volume or area.
B_ACT
Beta Activity expressed in units of activity per volume or area.
DF
Decay Factor calculated using the half-life for the specific routine. The
decay factor is calculated from the midpoint of the count time to the
date and time of the sample collection.
VOL
Sample Volume expressed in defined output units.
VOL_IN
Input Sample Volume as entered by the operator
CF
Input Volume Conversion Factor. The value depends on the input units
and the output units selected.
ACF
DPM to activity units conversion factor. Value depends on the units
specified in the Define Counting Routine.
