Problem 50

Nitrogen-13 is a 9.97-min-half-life isotope used to tag ammonia for PET scans, including quantification of myocardial infarction. Consider an intravenous injection incorporating 20.0 mCi of N-13. Plot a graph of N-13 activity versus time, with your vertical axis logarithmic and your horizontal axis linear. Why is the graph a straight line? Whats the significance of its slope?

Step-by-Step Solution:
Step 1 of 3
