Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.

Since atmospheric carbon 14 arises at about the same rate that the atom decays, the Earth's levels of carbon 14 have remained constant.

Suess explained the phenomenon by the fact that the increased industrial use of fossil carbon in coal and in oil changed the ratio between the dead carbon C12 and the C14 (radiocarbon) in the atmosphere and therefore also in the biosphere.

The lab also provides stable isotope analyses on a standalone basis.

Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).
