To carry out this sensitivity correction, a so-called test dose, which remains constant during the whole protocol, is administered after measuring each regenerative including natural and zero dose Fig. Values above zero indicate that an punkte z.

For the palaeodose val- ues determined using any of these approaches standard deviation and standard error are then determined cf. Most studies that have reported signifi- cosmic radiation and can be estimated from cant thermal transfer are related to quartz with geographic position and burial depth of the a young sedimentary history, i. Stimulating these mineral grains using either light blue or green for OSL; infrared for IRSL or heat for TL causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral.
