Radioactive dating



How Is Radioactive Dating Used to Date Fossils?

One of the most commonly used methods for determining the age of fossils is via radioactive dating a. Radioisotopes are alternative forms of an element that have the same number of fossll but a fossil dating radioactive isotopes number of neutrons. There are three types of radioactive decay that can occur depending on the radioisotope involved: Alpha radiation can be stopped by paper, beta radiation can be stopped by wood, while fossil dating radioactive isotopes radiation is stopped by lead.

Types of Radioactive Decay. Radioisotopes decay at a constant rate and the time taken for fsosil the original radioisotope to decay is known as the half life. While radioisotope dating is the most commonly used method for dating fossils, other techniques do exist.

Alpha decay — Atom releases two protons and two neutrons alpha particle to form raadioactive new, more stable element Beta decay — A neutron decays to produce a proton, electron and anti-neutrino electron is released and a datkng element forms Gamma decay — Involves the release of electromagnetic radiation gamma raysbut does not change the mass of the atom Alpha radiation can be stopped by paper, beta radiation can be stopped by wood, while gamma radiation is stopped by lead Types of Radioactive Decay.
