A bottle of red wine is thought to have been sealed about `5 years` ago. The wine containa a number of different kinds of atoms, incluing carbon, oxygen,and hydrogen. Each of these has a radioactive isotope. The radiaoctive isotope of carbon is the familiar `._6^(14)C` with a half-life of `5730 years`. The radioactive isotope of oxygen is. `._(8)^(15)O` and has a half-life of `122.2 s`. The radioactive isotope of hydrogen `._1^(3)H` and is called tritium, its half-life is `12.33 years`. The activity of each of these  isotopes is known at the time the bottle was sealed. However, only one of the isotopes is useful for determining the age of the wine accurately. Which is it?
