The age of water or wine may be determined by measuring its radioactive tritium(3H) content. Tritium, present in a steady state in nature, is formed primarily by cosmicirradiation of water vapor in the upper atmosphere, and it decays spontaneously by a firstorder process with a half-life of 12.5 years. The formation reaction does not occursignificantly inside a glass bottle at the surface of the earth.
Calculate the age of a suspected vintage wine that is 20% as radioactive as a freshly bottled specimen. Radioactivity follows first order rate kinetics.
