For radioactive decay the rate constant k is called the decay constant. All living things are in equilibrium with 14C in the atmosphere. When something dies it stops absorbing 14C and the present 14C starts to undergo beta decay. The half-life 14C decay is 5.73 x 103 years. Rate of radioactive decay is measured in disintegrations per minute per gram (d/min•g). In living things 14C activity is measured to be 14 (d/min•g). This video contains an example problem where carbon dating is used to predict the age of an item.
