Carbon dating used today

Radiocarbon dating is a method of estimating the age of organic material.

It was developed right after World War II by Willard F.

However, radioisotope dating may not work so well in the future.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

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.
