Section 2. Acquiring and Processing Thermoluminescence Data#

2.1 Project Planning and requirements#

The requirements of a project planning are not standard and can vary depending on various factors, such as the size and/or available mass of the sample, desired precision, the sampling procedure, the archaelogist's estimation of the object's age. All the above information are significant and will determine the protocol/technique that will be used for the TL measurement (fine grain, coarse grain etc), the number of the sub-samples (aliquots) that will be prepared and the doses that will be applied for the calibration.

2.2 Sources of data and file types#

Production of TL data is accomplished worldwide either by commercially available or custom made instruments. As a result, both the source (platform or software) and the type of the data are instrument dependent and proprietary. All the same, in all cases, the TL-data can easily be converted to an ASCII text format, which allows their easy processing with spreadsheet programs, such as MS Excel. A difference, however, can be the ability of the various types of software used to store along with the data, the measurement-associated metadata, which could hamper or even block their comparison with other TL-data.
