The most common types of radioactivity are α decay, β decay, γ emission, positron emission, and electron capture.

Nuclear reactions also often involve γ rays, and some nuclei decay by electron capture.

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.Radioactive dating of rock samples determines the age of rocks from the time it was formed.Geologist determine the age of rocks using radioactive dating.All nuclear decay processes follow first-order kinetics, and each radioisotope has its own characteristic half-life, the time that is required for half of its atoms to decay.

Because of the large differences in stability among nuclides, there is a very wide range of half-lives of radioactive substances.

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).
