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. Each of these modes of decay leads to the formation of a new stable nuclei sometimes via multiple decays before ending in a stable isotope. All nuclear decay processes follow first-order kinetics and each radioisotope has its own half-life.

Half-life (t1/2) is the time required for one half of the nuclei in a sample of radioactive material to decay. After each half-life has passed, one half of the radioactive nuclei will have transformed into a new nuclide.

For a 0th order reaction, the half-life decreases as concentration decreases. For a 1st order reaction, the half-life is constant and independent of concentration, while for a 2nd order reaction, the half-life increases with decreasing concentration.

The reason this process works is because when organisms are alive they are constantly replenishing their C-14 supply through respiration, providing them with a constant amount of the isotope. However, when an organism ceases to exist, it no longer takes in carbon from its environment and the unstable C-14 isotope begins to decay.
