Two archeological ceramic sherds in a single quartz aliquot form have been dated success-fully for the first time, by the newly developed method of optical stimulated luminescence OSL with green light-emitting diodes LED. Comparison with the conventional thermoluminescence TL method provided ages of the same order of magnitude. The ceramics come from two recently excavated sites at Hellenikon and Ligourio in Argolid, Peloponnese, Greece. One sherd dates from the end of 4th millenium B. The new method of nuclear dating is described in the paper and appropriately evaluated. Sign in Sign up. Advanced Search Help. Sign in Sign up My Content You’re not logged in.

We describe data on the thermoluminescence TL of ocean sediments which leads us to propose that exposure to sunlight prior to deposition reduces any previously acquired TL to a small “residual” value. Subsequent radiation from radionuclides in the sediment increases the TL and this increase is used for dating.
Three methods of separating these two TL components are described. An equation relating this dose to the age and to dose rates derived from radioactivity analyses is presented. The TL age uncertainty is primarily set by the uncertainty in the water content. Olav B. Lian , Jinsheng Hu , D.
Reliability of thermoluminescence dating of stalagmitic calcite
Thermoluminescence TL dating of sediments is based on the observation that exposure of quartz and feldspar to sunlight rapidly reduces the TL level to a small residual value. Therefore, sediments transported by air or water will usually be deposited with a very small TL level. When the sediment has been covered as a result of subsequent sedimentation, the TL level again increases with time as a result of exposure of the minerals to the natural background radiation.
The TL level is thus a measure of the accumulated radiation dose the palaeodose , and the time elapsed since sedimentation is given by the ratio of the palaeodose to the annual dose.

The potential of thermoluminescence measurements of bricks from the contaminated area of the Techa river valley, Southern Urals, Russia, for reconstructing external exposures of affected population groups has been studied.
Thermoluminescence dating of background samples was used to evaluate the age of old buildings available on the river banks. The anthropogenic gamma dose accrued in exposed samples is determined by subtracting the natural radiation background dose for the corresponding age from the accumulated dose measured by thermoluminescence. For a site in the upper Techa river region, where the levels of external exposures were extremely high, the depth-dose distribution in bricks and the dependence of accidental dose on the height of the sampling position were determined.
For the same site, Monte Carlo simulations of radiation transport were performed for different source configurations corresponding to the situation before and after the construction of a rt-servoir on the river and evacuation of the population in A comparison of the results provides an understanding of the features of the measured depth-dose distributions and height dependencies in terms of the source configurations and shows that bricks from the higher sampling positions are likely to have accrued a larger fraction of anthropogenic dose from the time before the construction of the reservoir.
Examining Thermoluminescence Dating
Luminescence is exhibited by many common minerals, some of which have been exploited for dating. Calcite has the potential to date events that occurred over millions of years, but a series of challenges has hindered its use in dating limestone building stones, speleothems, and mollusk shells. Now, however, promising results from calcite luminescence dating have been achieved from an unexpected source: the opercula grown by certain species of snail.
Luminescence thermochronometry is a recently developed method that can constrain erosion histories at sub-Quaternary timescales. Luminescence thermochronometry determines the timing and rate at which electrons are trapped and thermally released in minerals, in response to in situ radiation and rock cooling. In this article, we use examples of luminescence thermochronometry applied to the Himalaya mountains, the New Zealand Alps and the Japanese Alps to infer and link together wider aspects of regional erosion, climate and tectonic activity.

Due to this fact it could be considered as little effective in case of such sites from the Roman period as burial grounds with many artefacts useful for archaeological dating. However, for many settlements from this period, where pottery is the only kind of artefacts, the TL method can give notable results. It turned out that clay daub is an equally good dating material as pottery. It can be found that the TL dating of pottery from Nieszawa Kolonia confirms two stages of settlement.
The second group of TL dates corresponds to the phases C2D that is to the second stage of settlement, from the second half of the 3rd century to the half of the 5th century AD.

Over the last 60 years, luminescence dating has developed into a robust chronometer for applications in earth sciences and archaeology. The technique is particularly useful for dating materials ranging in age from a few decades to around ,—, years. In this chapter, following a brief outline of the historical development of the dating method, basic principles behind the technique are discussed.

The two standard methods have been acknowledged in domain of TL dating and are used widely for age determination in archaeology and geology. As a dating tool the TL technique has been of great success in authentication of ancient ceramic art objects. However, a few complicated factors limit the precision and accuracy in age determination. These complicated factors are analyzed and discussed.
Therefore, although ceramic TL dating can in general solve the problem of authentication of ancient ceramics, there are still complexities that require further research and study. This is a preview of subscription content, log in to check access.

Canadian Journal of Earth Sciences ; 15 12 : — The basic thermoluminescence TL characteristics relevant to dating Quaternary calcite are reviewed and modifications of the basic TL age equation due to the effect of uranium series disequilibrium are discussed. Tentative explanations for these discrepancies are put forward, the most probable being sample inhomogeneity.
