tips for dating a recently divorced woman - Origin of carbon 14 dating

An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.

It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.

When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).

Well, if carbon-14 can decay into nitrogen-14 and other stuff, then we can create carbon-14 by combining nitrogen-14 with the proper stuff.

In this case, that happens to be a neutron, which allows us to do this: (a.k.a., carbon dioxide) and mixing throughout the atmosphere and oceans, easily making its way into living organisms into a well-understood equilibrium.

Carbon-14 is radioactive, with a half-life of about 5,700 years.

For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works.

But that doesn’t seem likely; there is data from North American and European trees that this is consistent with!

If this confirmed, then there was very likely an extremely large increase in cosmic radiation over a very short period of time, the likes of which we’ve never seen or recorded, until now.

­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.

About 1.1% of all carbon is Carbon-13, with one extra neutron.
