Carbon dating equation
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.
This process is constantly ongoing, so that at any point in time the amount of carbon-14 in living plants is the same as the amount of carbon-14 in the air around them.
Living plants are active components of the overall food chain.
This rather complex formula shows you how to solve this puzzle using accepted scientific methods.
Half-life is defined as the amount of time it takes a given quantity to decrease to half of its initial value.
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.
After 5600 years, if we start with a gram, we end up with half a gram.
Since it is radioactive, it gradually fades away by radioactive decay until it is all gone.
Radiocarbon dating uses carbon-14 to determine the last time something (or someone) was alive.
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.
