Carbon dating equation edmonton alberta adult dating
The term is most commonly used in relation to atoms undergoing radioactive decay, but can be used to describe other types of decay, whether exponential or not.
One of the most well-known applications of half-life is carbon-14 dating.
Their bodies are said to be in “equilibrium” with carbon-14 in the air.
Although carbon-14 is radioactively decaying away in the body, it is constantly being replaced by new photosynthesis or the ingestion of food, leaving the amount relatively constant.
If you have a fossil, you can tell how old it is by the carbon 14 dating method.
This is a formula which helps you to date a fossil by its carbon.
The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to around 50,000 years ago.
A radiocarbon dating laboratory is able to measure the amount of carbon-14 remaining in a fossil.
When a plant stops assimilating carbon dioxide or when an animal or human being stops eating, the ingestion of carbon-14 also stops and the equilibrium is disrupted.
From that time forward, the only process at work in the body is radioactive decay.
Radiocarbon immediately reacts with oxygen in the air to form carbon dioxide (CO2).
This carbon dioxide rapidly mixes throughout the atmosphere, where at ground level it is taken in by plants during photosynthesis.
