Select all that apply. Which findings during visual quality control of a prepared radiopharmaceutical should prompt further evaluation before administration?  

BONUS QUESTION: +5 POINTS You’re free to answer it or skip it — any points you earn will be added later.   Using the decay chart or half-life provided, answer the following question:   Co57 Decay Chart.pdf   Cobalt 57 is often used as a source for gamma camera quality control due to its long half-life and energy peak similar to Tc99m. Due to sensitivity and increased time, a nuclear medicine department is able to use a Co57 source for QC until it has roughly only 5 mCi remaining. A typical Co57 source is calibrated with 20 mCi. How long will a department be able to use a source for QC? This box is free text. Label your answer with units. Round to one decimal place.

A dose of Tl-201 must contain 120 mCi at 1600 on Tuesday. How many mCi must be present in the vial when it is prepared at 0400 on Sunday? The one-hour decay factor for Tl-201 is 0.992.  

Which statement correctly describes positron annihilation?  

Which finding is an example of a radiochemical impurity?  

Nuclear reactors commonly produce neutron-rich radionuclides through neutron bombardment or fission.  

Match each type of purity with the finding it evaluates.
