Hence the term radioactive decay

Advantages of using radiocarbon dating

Radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate. The isotopic age then is called a cooling age. 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. The introduction of an instrument called an accelerator mass spectrometer has brought about a major advance in radiocarbon dating.

The isotopic age then is

Once dissolved, the sample is ready for the chemical separation of the dating elements. It is not possible simply to count the atoms, because all atoms loaded into the source do not form ions and some ions are lost in transmission down the flight tube.

These include the uranium-thorium method, the potassium-argon method, and the rubidium-strontium method. This beam is passed through a strong magnetic field in a vacuum, where it is separated into a number of beams, each containing atoms of only the same mass. Measurement of the time it takes for one-half of a radioactive substance to decay. The technique has potential applications for detailing the thermal history of a deposit.

Thus, the growth pattern of a tree of a known age can be used as a standard to determine the age of similar trees. Instead, they are a consequence of background radiation on certain minerals. The basic equation of radiometric dating requires that neither the parent nuclide nor the daughter product can enter or leave the material after its formation. Similarly, pollen grains released by seed-bearing plants became fossilized in rock layers.
