All amino acids except glycine the simplest one are optically active , having an asymmetric carbon atom. The amount of luminescence released is used to calculate the equivalent dose De that the sediment has acquired since deposition, which can be used in combination with the dose rate Dr to calculate the age. Radiation levels do not remain constant over time. Please help improve this section by adding citations to reliable sources. This process frees electrons within minerals that remain caught within the item. Currently, the maximum for fully anchored chronologies is a little over 11, years from present.
