If either assumption is wrong carbon-14 dating doesn't work.
This means that although they are very similar chemically, they have different masses.
ANSWER: To understand how carbon 14 dating works, you first have to understand what carbon-14 is and what part it plays in our biosphere. As they live and grow and interact with their environments they consume more and more carbon.
By far, the most abundant form of carbon is carbon-12.
Professor Willard Libby produced the first radiocarbon dates in 1949 and was later awarded the Nobel Prize for his efforts.
Radiocarbon dating works by comparing the three different isotopes of carbon.
The total mass of the isotope is indicated by the numerical superscript.
While the lighter isotopes C has decayed that what remains can no longer be measured. In 5,730 years half of the C in the atmosphere, and therefore in plants and animals, has not always been constant.
A basket is made of wood, or straw, or something that was once a living, breathing plant.
Yes, the decay of isotope 14 starts the moment the plant dies, which is before the moment the basket was made ...
Carbon-14 is radioactive, with a half-life of about 5,700 years.
For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works.
Since carbon-12 doesn't naturally decay while carbon-14 does, once a creature stops incorporating more carbon into its body, the ratio of carbon-12 to carbon-14 in its body begins to change, with less carbon-14 per carbon-12 as time passes.
