Radiocarbon dating is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. It can be used on objects as old as about 62,000 years.

## What is meant by carbon dating explain its uses?

Carbon dating, or radiocarbon dating, is a method used to date materials that once exchanged carbon dioxide with the atmosphere. Carbon dioxide in the atmosphere contains a constant amount of carbon-14, and as long as an organism is living, the amount of carbon-14 inside it is the same as the atmosphere.

## What is carbon dating short note?

From Wikipedia, the free encyclopedia. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.

## Why is carbon 14 not useful in nuclear medicine?

Answer: It is all to do with the emitted radiation and the half-life of the source. Carbon 14 is a beta emitter with a half-life of 5570 years. Of course a small fraction of the carbon atoms in your body are carbon 14 so you are already radioactive!!
