INTRODUCTION 

Time Activity Analysis (TAA) permits the user to make repeated measurements at timed 
intervals. It provides control over ROI, live time and real time for counting. The data can be 
viewed as raw counts or decay corrected and displayed either in a graph or tabular form.

3000 Main screen. Figure 12-1  Time Activity Analysis screen will appear. The functions at 
the bottom of the screen are disabled until the required parameters have been entered. 
When counting is started, a live spectrum is displayed in the upper half of the screen. The 
elapsed real and live time is displayed at the upper right of the screen as the counting 
progresses. Below the displayed time, there are options for viewing and displaying the data.
