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...

"What do you think is the ideal number of children for a family to have?" A poll asked this question of 1010 randomly chosen adults. Slightly less than half (48%) thought that a total of two children was ideal. Suppose that p = 0.48 is exactly true for the population of all adults. The polling company announced a margin of error of ±4 percentage points for this poll. What is the probability that the sample proportion p̂ for an SRS...
