The energies involved are so large, and the nucleus is so small that physical conditions in the Earth (i.e. The rate of decay or rate of change of the number N of particles is proportional to the number present at any time, i.e.

The half-life is the amount of time it takes for one half of the initial amount of the parent, radioactive isotope, to decay to the daughter isotope.

(For brevity's sake, hereafter I will refer to the parent isotope as ).

CDIAC's data holdings include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; and global/regional climate data and time series.

Isochron methods avoid the problems which can potentially result from both of the above assumptions.

Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.

, that is formed during respiration, combustion, and organic decomposition, is an essential component in photosynthesis, and is used in food refrigeration, carbonated beverages, inert atmospheres, fire extinguishers, and aerosols. (Elements & Compounds) a colourless odourless incombustible gas present in the atmosphere and formed during respiration, the decomposition and combustion of organic compounds, and in the reaction of acids with carbonates: used in carbonated drinks, fire extinguishers, and as dry ice for refrigeration. Also called: carbonic-acid gas , that is present in the atmosphere and is formed when any fuel containing carbon is burned.

It is breathed out of an animal's lungs during respiration, produced by the decay of organic matter, and used by plants in photosynthesis.The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.
