# Exponential decay carbon 14 dating formula

The ratio of carbon-12 to carbon-14 at the moment of death is the same as every other living thing, but the carbon-14 decays and is not replaced.

The carbon-14 decays with its half-life of 5,700 years, while the amount of carbon-12 remains constant in the sample.

Suppose the clay is in a pipe and as the kerosene flows through the pipe, every foot of clay removes 20% of the pollutants, leaving 80%.

If feet of pipe can be represented by the following equation: Suppose that the pollutants must be reduced to 10% in order for the kerosene to be used for jet fuel.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.

If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze.

In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years.

Natasha Glydon Exponential decay is a particular form of a very rapid decrease in some quantity.

Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon.

At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues.

One specific example of exponential decay is purified kerosene, used for jet fuel.

The kerosene is purified by removing pollutants, using a clay filter.
