Thermoluminescent dosimeter

A thermoluminescent dosimeter (TLD) is a type of radiation detector worn by radiation workers to measure their radiation dose. It is a well-established dosimetric technique with applications in personal, environmental, clinical dosimetry, and radiation processing. The TLD measures ionizing radiation by measuring the amount of visible light emitted from a crystal in the detector when it is heated. X-ray film badges, TLD badges, and TLD ring dosimeters are commonly used to measure personnel whole-body and extremity radiation doses. There are various examination strategies concerning TLD materials and their TL behavior related to different radiation types, such as alpha, UV, gamma, neutron irradiation, etc.From: Handbook of Environmental Engineering [2019], Synthesis, characterisation and dosimetric evaluation of MgB₄O₇ glass as thermoluminescent dosimeter [2018], Comprehensive Brachytherapy [2019], Radiation Safety in Nuclear Medicine [2019], HCl-doped poly (para-nitro aniline-co-para-toluidine) thin film as a gamma ray dosimeter [2021]

TLD (thermoluminescent dosimeter)—Dosimetry device which allows measurement of dose by absorbing and “storing” energy deposited by radiation. The energy is released in the form of a measurable flash of light upon heating.

Thermoluminescent dosimetry (TLD) is a well-established dosimetric technique with applications in personal, environmental, clinical dosimetry and radiation processing. Thermoluminescence phenomena can be observed in numerous materials. However, only few materials show the properties required for radiation dosimetry, depending on specific dosimetric application. Numerous thermoluminescent (TL) materials are available commercially. However, due to some limitations, i-e energy dependence, complicated glow curves, low linear dose range, fading and complex thermal treatment, most of them have limited application scope. Ideally, a TL material should be tissue equivalent and highly sensitive with wide linear dose range having negligible fading and simple glow curve.
