IR-bleaching experiments were carried out to obtain information about the underlying physical processes of the IR-RL emission.
Forschungsstelle Archäometrie der Heidelberger Akademie der Wissenschaften am Max-Planck-Institut für Kernphysik, PF 103980, 69029 Heidelberg, ALLEMAGNEA new luminescence reader for radioluminescence (RL) measurements is presented.
The system allows detection of RL emissions in the near infrared region (IR).
The signal can be interpreted as the infrared (IR)-emitting electron transition into a light sensitive trap.
Direct measurement of the electron density is thus possible, and this is the basic advantage of this new method.
The intensity of blue, green or infrared light that is created when an object is stimulated is proportional to the number of electrons stored in the mineral's structure, and in turn those light units are converted to dose units.
