We present an overview of the technique, its advantages, assumptions and limitations. Radiocarbon has been applied to dating many historical artifacts and archaeological applications. PY - 2014Y1 - 2014N2 - Radiocarbon dating is an important tool for the determination of the age of many samples and covers the time period of approximately the last 50,000 years.
Some specific examples including dating of famous artifacts of artistic, religious and scientific interest are discussed. We can use radiocarbon dating to estimate the age of a wide variety of carbon-containing materials.
If you ever wondered why nuclear tests are now performed underground, this is why.
Most radiocarbon dating today is done using an accelerator mass spectrometer, an instrument that directly counts the numbers of carbon-14 and carbon-12 in a sample.
They have the same ratio of carbon-14 to carbon-12 as the atmosphere, and this same ratio is then carried up the food chain all the way to apex predators, like sharks.
But when gas exchange is stopped, be it in a particular part of the body like in deposits in bones and teeth, or when the entire organism dies, the ratio of carbon-14 to carbon-12 begins to decrease.
For example, age of the earth, moon, rocks, and mineral deposits can be determined by using the principle of radioisotopic dating.
The age of glaciers, snow fields, and even wines can be estimated by radioisotopic dating.
A detailed description of radiocarbon dating is available at the Wikipedia radiocarbon dating web page.
Bottom line: Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens from the distant past.

Radiocarbon dating or in general radioisotopic dating method is used for estimating the age of old archaeological samples. In the upper atmosphere, nitrogen (C in a living plant, were can estimate the age of the object (the age of the object means the number of years ago when plant should have died), by using the formula.
