Here's a kit preparation, decay, and particle size problem.

We'll cover this on Monday should you have any questions.

An elution vial contains 820 mCi in 5.6 mL at 600 hrs. How many mL are needed from the elution vial draw out 75 mCi at 7am which was compounded with a vial MAA to produce ^99mTcMAA. How much saline do you add to the MAA vial if you needed a total of 5 mL? If the vial contained 2.5 x 10⁶ particles and an adult dose administered at 8am was 5.2 mCi, how many particles did the patient receive? If another patient was injected at 12N and received a 5.4 mCi dose, how many particles did he/she receive?
