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.

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.

Dolutegravir-Based Regimen Ensures High Virological Success despite Prior Exposure to Efavirenz-Based First-LINE ART in Cameroon: An Evidence of a Successful Transition Model

Viruses, 2022
To ensure optimal prescribing practices in the dolutegravir-era in Cameroon, we compared first-line virological response (VR) under tenofovir + lamivudine + dolutegravir (TLD) according to prior exposure to tenofovir + lamivudine + efavirenz (TLE).

The effects of heating rate on the dose response characteristics of TLD-200, TLD-300 and TLD-400

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2009
Abstract In the given study; the effects of heating rates on the dose response characteristics of CaF 2 :Dy (TLD-200), CaF 2 :Tm (TLD-300) and CaF 2 :Mn (TLD-400) crystals have been investigated using the dose dependence curve and dose response function f ( D ). It was observed from the dose response functions that the linearity and behaviour of the
