Carbon dating procedure

The 14 in Carbon-14 means that the atomic weight of the carbon atom is 14 atomic mass units (AMU).A proton has an atomic mass of 1 AMU and a neutron has a mass of 1 AMU. It decays with Beta Minus (B-) decay with a half-live of about 5700 years.The sample is ionized using the ionic generator and then passed through a magnetic field that separates the samples into different groups based on their mass and ionization levels.When each ionized sample reaches the Faraday Cup in which it is stored, a current is produced and measured as an electrical signal.Mass spectrometers can be used to measure isotopic samples as small as one 1 nanogram.Mass spectrometers are made up of an ion generator, analyzer, and several detectors.Animals and people eat plants and take in carbon-14 as well.The ratio of normal carbon (carbon-12) to carbon-14 in the air and in all living things at any given time is nearly constant.

While not all objects have the same isotopes, both living and nonliving objects have some sort of decaying, radioactive isotope that can be used based on known decay rates. An isotope of some sort is located and isolated within an object.Measuring the amount of this element in an item helps determine how old it is...i hoped that help because it sure did for me and my homework!!!Archeologists use the method of Carbon 14 dating to determine the age of any biological relic containing some carbon.Carbon 14 is an isotope of carbon made in Earths upper atmosphere and it has a half life of 5730 years, enabling dating back to about…
