Thermoluminescence of Lunar Samples

Science, 1970
Appreciable natural thermoluminescence with glow curve peaks at about 350 degrees centigrade for lunar fines and breccias and above 400 degrees centigrade for crystalline rocks has been recognized in lunar samples. Plagioclase has been identified as the principal carrier of thermoluminescence, and the difference in peak temperatures indicates ...

On the Thermoluminescence Characteristics of NAF and KCL

Applied Radiation and Isotopes, 2023
Thermoluminescence (TL) properties of NaF and KCl are investigated in order to assess their suitability as radiation dosemeters for retrospective dosimetry. TL measurements were made on samples irradiated to different doses (1-20 Gy) and heated at a rate ranging from 0.4 to 4 °C/s in a TL/OSL reader.

Thermoluminescence of Biological Materials

Nature, 1970
THERMOLUMINESCENCE may be observed from many chemical compounds, both in crystalline and in amorphous form. The compounds so far investigated have usually been mineral or synthetic materials, but there is no reason to suppose that the various salts deposited in biological materials have a structure excluding this property.

Thermoluminescence emission spectrometer

Applied Optics, 1988
A sensitive thermoluminescence (TL) emission spectrometer based on Fourier transform spectroscopy is described. It employs a modified scanning Twyman-Green interferometer with photomultiplier detection in a photon-counting mode. The etendue is 180pi mm(2), and it covers the 350-600-nm wavelength range.

Thermoluminescent Properties of Topaz

Health Physics, 1978
AbstractThe possibility of using naturally occurring topaz crystals as a thermoluminescent dosimeter (TLD) was investigated. Topaz crystals are small, durable and possess thermoluminescent characteristics which compare favorably with existing commercial materials.

Thermoluminescence of Biological Materials

Nature, 1971
THERMOLUMINESCENCE (TL) of fossil bones and of various kinds of recent biological material has been reported by Jasinska and Niewiadomski1, who suggest that such materials could be used for dating purposes, but draw attention to difficulties which arise due to tribothermoluminescence (TTL, which is thermoluminescence derived from the mechanical energy ...

THERMOLUMINESCENCE FROM UNIRRADIATED FLINTS: REGENERATION THERMOLUMINESCENCE

Archaeometry, 1972
ABSTRACTSThe ‘spurious’thermoluminescent glow from ground samples of flint is responsible for dating errors in the region of 10 000 years for grains less than 45 μm diameter or of 4000 years for larger grains. The glow is partly tribothermoluminescence and partly regeneration thermoluminescence and the conditions in which these arise or are accelerated

Instrumentation in Thermoluminescence Dosimetry

Radiation Protection Dosimetry, 1986
Abstract In the performance of a thermoluminescence dosimetry (TLD) system the equipment plays an important role. Crucial parameters of instrumentation in TLD are discussed in some detail. A review is given of equipment available on the market today - with some emphasis on automation - which is partly based on information from ...

Thermoluminescence of meteorites

Journal of Geophysical Research, 1966
The experimental techniques used for measuring thermoluminescence are described. The glow curves of achondrites differ markedly from subclass to subclass in their artificially excited glow curves. A fair correlation exists between the radiation ages and the luminescence intensity. The olivine components of pallasites yield very low luminescence whereas

Thermoluminescence in medical dosimetry

Applied Radiation and Isotopes, 2012
Thermoluminescence dosimetry (TLD) is applied worldwide for personal and medical dosimetry. TLD method has resulted in many interesting findings in medicine as TL dosimeters have many relevant advantages such as high sensitivity, small physical size, tissue equivalence, etc.
