Thermoluminescence dating cost
Result provides a statement on the last time of firing.The age specification contained in the TL expertise refers to the so-called “firing age” of the sample(s) (minerals), i.e.The laboratory also collaborates with the Department of Earth and Space Sciences for geological applications. James Feathers (Ph D, University of Washington 1990) is director of the laboratory.He is a professionally trained archaeologist with an interest in dating methods.A precise evaluation of the gamma radiation energy is only possible when the exact geological conditions at the location of origin of the examined find are known.
( Error factor under 0,1 % ) The TL-Report do not provide on the investigation of polymers (synthetic and natural resins) of all kinds.
the name already indicates that an archaeological, i.e.
historical aging has been registered since the last firing of the object. The ‘neutral energy ‘ – ß or NTL ß (alpha) which is the amount of energy emitted by the same material after renewed exposure to radiation from a gauged radioactive source. The ‘annual energy rate ‘ or J D/ D which represents the annual increase of accumulatively stored energy.
Condition and restauration on the objects can be proofed by separate methods!!
The laboratory requires two photos for the compilation of a Tl expertise.
In order to determine the ‘annual energy rate and thereby the exact age of an object, the object specific energy output of the three basic radiation types; alpha, beta and gamma rays, has to be defined.
