Section 7.4: Exponential Growth and Decay
sites.radford.edurays converts nitrogen to a radioactive isotope of carbon, 14C, with a half life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon and the amount of 14C begins to decrease through radioactive decay ...
