It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge.
But when the organism dies, the amount of C-14 begins to decrease.
Plants absorb C-14 during photosynthesis, so C-14 is incorporated into the cellular structure of plants.
Plants are then eaten by animals, making C-14 a part of the cellular structure of all living things.
This decay is an example of an exponential decay, shown in the figure below.
Knowing about half-lives is important because it enables you to determine when a sample of radioactive material is safe to handle.
