Thermoluminescence dating using fine grains from pottery

Most mineral materials, including the constituents of pottery, have the property of thermoluminescence (TL), where part of the energy from radioactive decay in and around the mineral is stored (in the form of trapped electrons) and later released as light upon strong heating (as the electrons are detrapped and combine with lattice ions).Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.

Drilling, the usual method of sampling, introduces some uncertainty.

It is also rare that any information about the radiation from the burial soil can be obtained, as art objects are usually thoroughly cleaned.

The TL laboratory at Daybreak was established in 1977 to make TL available to the art community in general. Studies at Oxford back in the 70s on Romano-British pottery indicated that when all quantities entering the age equation are measured, the TL date of a single potsherd will typically fall within 15 per cent of the known date.

When dates of a number of sherds associated together are averaged, the error is reduced typically to 7-10 per cent. The succeeding 30 years, and increased understanding of the dosimetry, have not brought much improvement.
