Carbon-14 is produced in the upper atmosphere when cosmic rays produce thermalised neutrons, by hitting atomic nuclei. If these thermalised neutrons then hits a Nitrogen neuclei it creates Carbon 14.

Radioactive carbon-14 is constantly being produced today how does this happen?

It is produced in the atmosphere, by radiation from outer space.

Carbon-14 is produced in the atmosphere principally by?

Carbon 14 is an isotope of cosmogenic origin; the reaction is: 1n + 14N → 14C + 1p

How is carbon-14 produced?

Carbon-14 forms in the upper atmosphere, when a nitrogen atom is converted to an atom of carbon and atom of hydrogen by the addition of a neutron; 14N + 1n ---> 14C + 1H.

What is C-14?

Carbon-14 (C-14) is a rare isotope of carbon produced in the upper atmosphere when a cosmic ray strikes an atom of nitrogen. Carbon-14 is radioactive undergoing beta decay to nitrogen-14 with a halflife of 5570 years. Because it is produced at a near constant rate and living organisms maintain the same percentage of it as is present in the atmosphere while they are alive, but after an organism dies it can no longer equalize the amount of the carbon-14 in its tissues, this isotope's decay can be used as a "clock" to measure the time since the organism died.

Why is carbon-14 found in all living things?

Carbon-14 is produced by the effect of solar radiation on nitrogen-14 in the atmosphere. This is then incorporated into plants during the process of photosynthesis. Animals eat plants (and/or other animals that have eaten plants), so carbon-14 gets into their bodies as well.

What are the naturally occurring isotopes of carbon?

Carbon-12 (98.93%), Carbon-13 (1.07%), and Carbon-14 (1 PPT) all occur naturally. However, Carbon-14 is radioactive (halflife 5,730±40 years) and is being produced only high in the atmosphere by bombardment of nitrogen gas by cosmic rays.

What gas was not found in earths early atmosphere but was produced by photosynthesis?

Carbon dioxide

What is carbon dating and how does it work?

This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14. C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope). The new isotope is called

Do carbon 14 levels in the atmosphere change over time?


Where does carbon 14 occur?

in the atmosphere, in living things, in dead things.

How is carbon-14 produced and where does it exist naturally?

"It is produced naturally in the upper atmosphere by the action of cosmic rays on nitrogen 14 atoms. The reaction is given in the linked article. Once produced, the atoms diffuse down to the biosphere, where it gets incorporated into all living things. Rock deposits that contain carbon, including oil and gas deposits, do not contain any carbon-14: with a half life of 5730 years, it has already decayed. It only makes up about 1 part-per-trillion of carbon on the Earth."
