Atmospheric nuclear weapon tests almost doubled the concentration of The above-ground nuclear tests that occurred in several countries between 19 (see nuclear test list) dramatically increased the amount of carbon-14 in the atmosphere and subsequently in the biosphere; after the tests ended, the atmospheric concentration of the isotope began to decrease.One side-effect of the change in atmospheric carbon-14 is that this has enabled some options (e.g., bomb-pulse dating Carbon-14 is produced in coolant at boiling water reactors (BWRs) and pressurized water reactors (PWRs).Here is the equation for that radioactive decay: [215/84]Po [4/2]a" title="Alpha decay" height="32" width="184"In beta decay, a neutron changes into a proton plus an electron. The electron leaves the atom with high energy as a beta particle.The nucleus has one more proton and one less neutron when it emits a beta particle.The resulting daughter nucleus is of an element 2 positions to the left of the 'parent' in the periodic table.When beta decay occurs a neutron within the nucleus emits the particle and changes into a proton.C, or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.

Before and after emission of the gamma ray they are the same isotope of the element but they are different nuclide because the term nuclide incorporates nuclear energy states as well basic structure.

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

The resulting neutrons ( but attempts to directly measure the production rate in situ were not very successful.

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

Plants fix atmospheric carbon during photosynthesis, so the level of C level for the calculation can either be estimated, or else directly compared with known year-by-year data from tree-ring data (dendrochronology) up to 10,000 years ago (using overlapping data from live and dead trees in a given area), or else from cave deposits (speleothems), back to about 45,000 years before the present.
