Thermal quenching of thermoluminescence in TLD-200, TLD-300 and TLD-400 after β-irradiation

Physica B: Condensed Matter, 2011
Abstract The dosimetric characteristics of many TL materials are influenced by changes in location, size and shape of the glow curves due to changes in the heating rate. In this study, the effect of heating rate on the integrated peak areas of CaF 2 :Dy (TLD-200), CaF 2 :Tm (TLD-300) and CaF 2 :Mn (TLD-400) crystals have been investigated after β ...

Treatment limitation decision in delirium: a secondary analysis of a prospective observational study [PDF]

BMC Medical Ethics
Background Treatment limitation decision (TLD) is a complex process affected by comorbidities and cultural aspects. We hypothesized that presence of delirium is associated with TLD in hospitalized patients. Objective to compare the proportion of patients

A method to modify the response of neutron dosimeters in the fields with energy spectra different from the calibration field [PDF]

Journal of Nuclear Research and Applications, 2021
One problem in neutron dosimetry is that dosimeter responses per unit dose-equivalent in measurement and calibration fields are different. Hence, the neutron dose suffers a large uncertainty.

Investigation of Thermal Quenching Effect for Lithium Fluoride (LiF) Type Dosimeters

Cumhuriyet Science Journal, 2023
Thermal quenching is described as a decrease in luminescence efficiency with increasing measurement temperature. Luminescence intensity decreases with increasing heating rates in the presence of thermal quenching.
