Monocot plants such as Allium and Colocasia are associated with underground structures for storage and/or asexual reproduction such as bulbs and corms respectively. 

Short Answer: A Tc-99m MAA kit is prepared at 0700 with 7.5 million particles. The kit contains 45 mCi of Tc-99m in a total volume of 12 mL. A 3 mCi dose is needed at 1200. How many MAA particles will be administered? Round your answer to the nearest 1,000 particles.

Which finding indicates a chemical purity problem in Mo-99/Tc-99m generator eluate?

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.

At 2000, would this eluate still be acceptable for use based on Mo-99 breakthrough limits?    

What is the Mo-99 breakthrough at the time of elution, expressed as µCi Mo-99 per mCi Tc-99m?  

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.

Short Answer: A vial of Ga-68 contains 6.0 Ci in 8.0 mL at 1030. What will the specific concentration of Ga-68 be at 1210? Convert your final answer to mCi/mL. Round to one decimal place.

A Mo-99/Tc-99m generator has 920 mCi of Tc-99m available for elution. If 760 mCi are recovered during elution, what is the elution efficiency?
