What radioactive decay is used in carbon dating

The rate at which the regeneration takes place has gone virtually unchanged for centuries; a feature which depends on the flux of particles bombarding the earth, and the strength of the magnetic field capable of diverting them.This magnetic shield, and consequently the particle flux, has slowly changed over time, and the quantity of carbon 14 formed on Earth changes with it.Dedicated at the University of Chicago on October 10, 2016.In 1946, Willard Libby proposed an innovative method for dating organic materials by measuring their content of carbon-14, a newly discovered radioactive isotope of carbon.Korff predicted that the reaction between these neutrons and nitrogen-14, which predominates in the atmosphere, would produce carbon-14, also called radiocarbon.Libby cleverly realized that carbon-14 in the atmosphere would find its way into living matter, which would thus be tagged with the radioactive isotope.

When a living organism dies, the radioactive carbon is no longer absorbed, and the ratio of carbon 14 present begins to decrease.Stages of Carbon-14 Formation Carbon-14 is continuously generated in the atmosphere by cosmic radiation.Neutrons are ejected from nuclei of the upper atmosphere in collisions with cosmic rays (A).The nucleus of carbon 14 contains 6 protons and 8 neutrons, as opposed to the 6 and 6 found in ordinary carbon 12.The imbalance makes carbon 14 a radioisotope with a half-life of 5,700 years, and an emitter of beta particles.
