So one would think that since the radiocarbon dating method works on organic (once-living) materials, then radiocarbon could be used to date fossils.Through photosynthesis carbon dioxide enters plants and algae, bringing radiocarbon into the food chain.Radiocarbon then enters animals as they consume the plants (figure 2).(This 5,730 year period is called the half-life of radiocarbon, figure 5).6 At this decay rate, hardly any carbon-14 atoms will remain after only 57,300 years (or ten half-lives). The decay of radiocarbon follows the exponential decay law, whereby the percentage decrease in the number of parent atoms per unit time is constant.
After each half-life of 5,730 years, the number of parent radiocarbon atoms remaining is halved.
Knowing the number of atoms that decayed in our sample over a month, we can calculate the radiocarbon decay rate.
