1) Assuming you start with 1 mCi 52Fe and no 52mMn, what will the activity of 52mMn be after 10 min? Answer in mCimCi.

2) What will be the activity in previous question after 20 minutes?

3) When will the activity of the sample be the highest, i.e. when is the best time to elute the sample?

4)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 52mMn be after 48 hours?

5) What is the activity of the 52Fe in Question 4 at this point?

82Rb with T1/2=1.25min, like 81Rb is a positron emitter that is useful for heart perfusion imaging. It can be produced by the natural decay of 82Sr  (T1/2=25 days). 1) Suppose you have a sample of with 100 mCi of 82Sr. When will the activity of 82Rb reach over 99% of the activity of 82Sr? 2) How much daughter activity (Question 1) will there be after 20 minutes? 3) How much daughter activity (Question 1) will there be after 20 days?

F.     A sample of Mn-56 is to have an activity of 105 Bq at the end of a 48 hour experiment. What mass of Mn-56 is required at the beginning of the experiment and what is its initial activity? The atomic mass of Mn-56 is 55.939 u. G.    Cl-37 is struck by a proton; the subsequent compound nucleus then ejects a 1 MeV neutron. There is no gamma emission in this reaction. The atomic mass of the product nucleus is...

Directions: You want to start by determining whether you are interested in working with a mean or a proportion. Then identify each of the parts listed below. 1. In order to use the formulas for a hypothesis test we first need to confirm that the appropriate assumptions are met. We need to confirm that we have a random sample and that the appropriate sample size requirements for the central limit theorem are satisfied. When working with a single mean we...

1) • z-value should be expressed to three decimal places: e.g., z=1.645. • Before you start each question, you should determine if you are dealing with the population mean or proportion since what you do depends on the type of parameter at hand. • When handling proportion problems, write/use/plug proportions as decimals (e.g., not 54%, but .54). • In the beginning, state clearly if you do a 1-tailed or 2-tailed test. State clearly your H0 and H1 using correct Greek...
