What is the activity quantity, for a experiment?

I will do an experiment with a radiotracer,99Tc. The detector is NaI 1"*1".
But I don't know how much of the radiotracer is nedded?

Solve mass specific activity for the detector's minimum detectable activity.

thank you. please more explain, with details.

To be more specific, you'll have to describe the experiment first. What do you want to measure where?

thank you. I will measure the residence time distribution in a straight pipe(2 meter). But I don't know how much of the radiotracer is needed
