The discussion revolves around determining the appropriate quantity of a radiotracer, specifically 99Tc, for an experiment involving a NaI detector. The focus is on the mass specific activity and its relation to the minimum detectable activity of the detector in the context of measuring residence time distribution in a straight pipe.
Participants express a need for more information about the experiment to provide accurate guidance, indicating that the discussion remains unresolved regarding the specific quantity of radiotracer needed.
The discussion lacks detailed assumptions about the experimental setup and the definitions of terms like "minimum detectable activity," which may affect the calculations and recommendations provided.
thank you. please more explain, with details.Doug Huffman said:Solve mass specific activity for the detector's minimum detectable activity.
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 neededmfb said:To be more specific, you'll have to describe the experiment first. What do you want to measure where?
