Uses of radioactive carbon dating

Radiocarbon dating or in general radioisotopic dating method is used for estimating the age of old archaeological samples. In the upper atmosphere, nitrogen ( Use of radioisotopic dating Radiocarbon dating or in general radioisotopic dating method is used for estimating the age of old archaeological samples.

It can be used on objects as old as about 62,000 years. Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.

Here’s an example using the simplest atom, hydrogen. Carbon-14 is an unstable isotope of carbon that will eventually decay at a known rate to become carbon-12.

Once an organism dies it stops taking in Carbon in any form.

The unstable Carbon-14 within the organism begins to decay to form Nitrogen-14 by emitting a beta particle.

Generally, however, they are useful because either we can detect their radioactivity or we can use the energy they release.

Radioactive isotopes are effective tracers because their radioactivity is easy to detect.

Bottom line: Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens from the distant past.
