Section 2. Acquiring and Processing Thermoluminescence Data#

2.1 Project Planning and Requirements#

The requirements for 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, and the archaelogist's estimation of the object's age. All such information is significant and will determine the protocol and technique that will be used for the TL measurement (e.g. fine grain, coarse grain, etc.), the number of 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 data are instrument dependent and proprietary. In all cases the TL-data can easily be converted to an ASCII text format, which allows easy processing within spreadsheet programs such as MS Excel. A difference, however, can be the ability of the various types of software used to store alongside the data the measurement-associated metadata, which could hamper or even block their comparison with other TL-data.
