Question

Gold - 198 is used in the diagnosis of liver problems. The half-life of^198 Au is 2.69 days. If you begin with 2.8 micrograms of this gold isotope, what mass remains after 10.8 days?
A researcher wants to use radioactive metals to label an enzyme that is found in high concentrations in cancer cells. Either ^64Cu or ^68Ga will bind with the enzyme. Suppose that you are the engineer assigned to this order by your company. What would you need to know about these isotopes and what questions would you ask the researcher to help with the selection.
