WebRadiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain. Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long WebRadiocarbon dating works by precisely measuring the ratio of radiocarbon to stable carbon in a sample. This is done in one of three ways: 1. Gas Proportional Counting, 2. Liquid Scintillation Counting, and 3. Accelerator Mass Spectrometry. The purpose in each of these methods is to determine the ratio of radiocarbon to stable carbon in the sample.
