1) If you inject 200 MBq of 18F into the body in the form of FDG, how many atoms of 18F will you have after 24 hours given that F decays into the stable nuclide 18O? The half-life of 18F is 1.83 hours. 214800000 atoms Submit (Survey Question) 2) Fe (T1/2 = 8.3 hr) is a generator that produces 52mMn (T1/2 21 min), a radionuclide which is ideal for myocardial imaging. After enough time, what kind of equilibrium will these fall into? Submit 3) Assuming you start with 1 mCi of $2Fe and no Mn, what will the activity of 52mMn be after 10 min? Answer in mCi. mCi Submit 4) What will be the activity in previous question after 20 minutes? mCi Submit 5) When will the activity of the sample be the highest, i.e. when is the best time to elute the sample? min Submit 6) Over the weekend there is no one working to elute the sample. Assuming you start with 1010 Bq of 52Fe and no 52mMn, what will the activity of 52 Mn be after 48 hours? Bq Submit 7) What is the activity of the 52Fe in Question 6 at this point? Bq Submit
