Wine can be dated by the amount of radioactive carbon from nuclear activity they containHarmless amounts of radioactive carbon have been found in wines made from grapes harvested since the last atmospheric atomic bomb tests were carried out in the 1960s.
But the "bomb pulse" of radioactive carbon lingering in the alcohol of wines produced since could be a good thing for wine dealers and collectors.
