Question Description

I need the solution for the problem. I have attached the png of the problem:

Lead (Pb) is often used as shielding for nuclear experiments because of its density and relative stability. There is a problem, however: several isotopes of lead are radioactive, deposited as part of heavier element decay chains. If the lead shielding in your experiment is radioactive, then it will interfere with your experiment! (a) Explain why it is difficult to separate different isotopes of lead from each other. (5 pts) (b) Show or explain why Pb-210 is the most problematic (with respect to shielding) natural radioactive isotope of lead. (hint: analyze the half-life of each isotope) (10 pts) (c) Assume that a particular 33 kg bar of lead was mined by ancient Romans in 50 B.C., with an initial Pb-210 activity of 0.74 bq per gram.2 This sample sank to the bottom of the Mediterranean Sea, protected from cosmic rays by water, where it remained until it was recently recovered. What is the current activity of Pb-210 in this lead bar?3 (10 pts
