Falicies of radioactive dating

Because of the fairly fast decay rate of carbon-14, it can only be used on material up to about 60,000 years old.Geologists use radiocarbon to date such materials as wood and pollen trapped in sediment, which indicates the date of the sediment itself.Beta radiation is a stream of electrons, called beta particles.When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit. Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm).

They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.When the unstable nuclei are prepared in the laboratory, the decomposition is called induced radioactivity.There are three major types of natural radioactivity: Alpha radiation consists of a stream of positively charged particles, called alpha particles, which have an atomic mass of 4 and a charge of 2 (a helium nucleus).Sedimentary rock is made of particles derived from other rocks, so measuring isotopes would date the original rock material, not the sediments they have ended up in.However, there are radiometric dating methods that can be used on sedimentary rock, including luminescence dating.
