Project Status; Source Decay - Troxler Enhanced RoadReader Plus 3451 Manual Of Operation And Instruction

PROJECT STATUS

The Data Manager provides a quick view of information on the
gauge, including the software version, serial number, type (length of
source rod and depth increments), count time, measurement units,
measurement mode, and depth mode. To view the gauge
information, press the 〈Project Status〉 button on the Print
Active Project Menu. The Data Manager software displays the
active setup, as shown in Figure 7–10.

SOURCE DECAY

As described earlier, the strength of radioactive material is measured
by its activity, or rate of decay. This activity decreases with time.
The Data Manager allows the operator to view how the decrease in
the radiation intensity of the source affects gauge measurements.
To view source decay information, press the 〈Source Decay〉
button on the Print Active Project Menu. The Data Manager
software displays the actual standard count, the predicted standard
count, and the difference between the counts (see Figure 7–11). The
gauge calculates the predicted standard count by correcting the
calibration standard count for source decay. For more information
on source decay, refer to page 3–27.
