Amino acid dating accuracy

The equations used by scholars to determine the date when the last exposure happened are typically: Where De is the laboratory beta dose that induces the same luminescence intensity in the sample emitted by the natural sample, and DT is the annual dose rate comprised of several components of radiation that arise in the decay of natural radioactive elements.See Liritzis et al.'s excellent 2013 book on Luminescence Dating for more information on these processes.Removal of carbonate contaminants through dilute acid washing is also not applicable because hydroxyapatite is acid soluble.Laboratories use the protein component of bone samples in AMS dating because it is relatively acid insoluble and, therefore, can be easily isolated from the hydroxyapatite component and other carbonates.The energy released by stimulating the crystals is expressed in light (luminescence).

If you can measure the rate of acquisition of the stored energy, you can figure out how long it has been since the exposure happened.

Luminescence dating is good for between a few hundred to (at least) several hundred thousand years, making it much more useful than carbon dating.

The term luminescence refers to the energy emitted as light from minerals such as quartz and feldspar after they've been exposed to an ionizing radiation of some sort.

This is because bones of animals or humans are often subjects of archaeological studies.

A lot about the prehistoric era has been learned due to archaeological studies and radiocarbon dating of bones.
