It is produced in the stratosphere and troposphere through the bombardment of waves of cosmic radiation on the element nitrogen-14.Neutrons from the cosmic radiation release the proton in nitrogen-14 converting it into carbon-14.(Hedman 2007)Counting atoms is no easy task; this is evident by how new of a technology radiometric dating actually is.The process is a complicated one and can only completed two ways.

Because the rate at which this activity decreases in time is known, the approximate age of the material can be...

A photosynthesizing plant does not strongly discriminate between the most abundant natural carbon isotope ( The discovery of natural carbon-14 by American chemist Willard Libby of the United States began with his recognition that a process that had produced radiocarbon in the laboratory was also going on in Earth’s upper atmosphere—namely, the bombardment of nitrogen by free neutrons.

Newly created carbon-14 atoms were presumed to react with atmospheric oxygen to form carbon dioxide...

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.

To understand radiocarbon dating, you first have to understand the word Although an element’s number of protons cannot change, the number of neutrons can vary slightly from each atom.

Carbon is such a common element but only a fraction of the carbon atoms are that of carbon-14.

The carbon would have to be separated from other isotopes as well, so that the readings were only being emitted by the carbon-14.

­The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.

Animals and people eat plants and take in carbon-14 as well.
