Atmospheric nuclear weapon tests almost doubled the concentration of 14C in the Northern Hemisphere. The above-ground nuclear tests that occurred in several countries between and see nuclear test list dramatically increased the amount of carbon in the atmosphere and subsequently in the biosphere; after the tests ended, the atmospheric concentration of the isotope began to decrease, as radioactive CO2 was fixed into plant and animal tissue, and dissolved in the oceans. One side-effect of the change in atmospheric carbon is that this has enabled some options e. The gas mixes rapidly and becomes evenly distributed throughout the atmosphere the mixing timescale in the order of weeks. Carbon dioxide also dissolves in water and thus permeates the oceans , but at a slower rate. The transfer between the ocean shallow layer and the large reservoir of bicarbonates in the ocean depths occurs at a limited rate. Such deposits often contain trace amounts of carbon The presence of carbon 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 14C content. what is carbon 14 dating used for.

For example, every person is hit by about half a million cosmic rays every hour. 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 seven protons, seven neutrons atom turns into a carbon atom six protons, eight neutrons and a hydrogen atom one proton, zero neutrons. Carbon is radioactive, with a half-life of about 5, years. For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works. Animals and people eat plants and take in carbon as well. The ratio of normal carbon carbon to carbon in the air and in all living things at any given time is nearly constant. Maybe one in a trillion carbon atoms are carbon
