Disadvantages of thermoluminescence dating
Ionizing radiation cases trapped electrons to accumulate and in laboratory before measuring radiation dose it is necessary to determine the time that has passed since zeroing event.
(Avvakumova, et al., 1990) The rate of radiation dose is estimated by measuring the alpha radioactivity of the sample material.
The device stores the radiant energy and later releases it in the form of visible or, in some cases, ultraviolet light.
Thermoluminescent dosimeter consists of a crystalline material which changes its color depending on the type of ionizing radiation.
In such a way, a flux of ionizing radiation is released both from natural radioactivity and cosmic radiation. The key advantages of the method are the following: long-term information storage, high sensitivity, registration of different radiation types, automatic data processing and automatic dose measurement. Thermoluminescence Detectors of Ionizing Radiation Based on Corundum Single Crystals with a Defective Structure. Many of our staff are international leaders in their fields and have key relationships with colleagues in other institutions and industries across the world.Staff members have been extremely successful in competitive research grants at a national level, and in attracting industry partnerships and funding.
Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. The technique has wide application, and is relatively cheap at some US$300–700 per object; ideally a number of samples are tested. The destruction of a relatively significant amount of sample material is necessary, which can be a limitation in the case of artworks.
