It is not affected by external factors such as temperature, pressure, chemical environment, or presence of a magnetic or electric field.

Finally, correlation between different isotopic dating methods may be required to confirm the age of a sample.

For all other nuclides, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time.

This predictability allows the relative abundances of related nuclides to be used as a clock to measure the time from the incorporation of the original nuclides into a material to the present.

This transformation may be accomplished in a number of different ways, including alpha decay (emission of alpha particles) and beta decay (electron emission, positron emission, or electron capture).

Another possibility is spontaneous fission into two or more nuclides.
