What type of dating is radioactive decay used for

The radioactive dating relies on spontaneous decomposition into other element. Carbon dating is one type of radiometric dating, there are others.

Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years.

The most common are protons, neutrons, positrons (which are positively charged electrons), alpha (α) particles (which are high-energy helium nuclei), beta (β) particles (which are high-energy electrons), and gamma (γ) rays (which compose high-energy electromagnetic radiation).

As with chemical reactions, nuclear reactions are always balanced.

(Recall that tritium is a radioactive isotope of hydrogen.) Tracers can also be used to follow the steps of a complex chemical reaction.

After incorporating radioactive atoms into reactant molecules, scientists can track where the atoms go by following their radioactivity.

Many of these substances have found useful applications in medical diagnosis and treatment, determining the age of archaeological and geological objects, and more.

Radioactive dating is used to find the absolute age of the rock in which the fossils are found, thus providing a fairly accurate age of the fossil.Each of these modes of decay leads to the formation of a new nucleus with a more stable n:p ratio.Some substances undergo radioactive decay series, proceeding through multiple decays before ending in a stable isotope.One excellent example of this is the use of carbon-14 to determine the steps involved in photosynthesis in plants.We know these steps because researchers followed the progress of carbon-14 throughout the process.

An atomic nucleus consists of protons and neutrons, collectively called nucleons.
