You have before you two glasses of Amontiallado wine- one made last year and one made many years ago.Tritium undergoes radioactive decay with a half-life of 12.33years.The glass on the left has sixty-four times fewer tritium counts than the glass on the right.
a. What is the age of the wine in the glass on the left, and the glass on the right?
b. What assumption(s) do you have to make in order to compare their tritium counts?
c. Is this an accurate assumption in light of the events of the post- World War II world?
