Carbon 14 used radiocarbon dating

Such deposits often contain trace amounts of carbon-14.

These amounts can vary significantly between samples, ranging up to 1% of the ratio found in living organisms, a concentration comparable to an apparent age of 40,000.), or other unknown secondary sources of carbon-14 production.

When cosmic rays enter the atmosphere, they undergo various transformations, including the production of neutrons.

The presence of carbon-14 in the isotopic signature of a sample of carbonaceous material possibly indicates its contamination by biogenic sources or the decay of radioactive material in surrounding geologic strata.

In connection with building the Borexino solar neutrino observatory, petroleum feedstock (for synthesizing the primary scintillant) was obtained with low Since many sources of human food are ultimately derived from terrestrial plants, the carbon that comprises our bodies contains carbon-14 at almost the same concentration as the atmosphere.

Liquid scintillation counting is the preferred method.

One of the frequent uses of the technique is to date organic remains from archaeological sites.
