摘要

目前的工作是利用热致发光技术（TL）研究用 β 射线辐照埃及麝香石矿物的剂量特性。使用（Tm - Tstop）和初始上升法对 TL 辉光曲线进行了分析。对麝香石辉光曲线的解卷积分析显示有八个叠加的陷波峰。这些陷波峰分别位于 0.72、0.80、0.98、1.09、1.19、1.30、1.50 和 1.59 eV。研究了剂量高达 330 Gy 的白云母样品，结果表明其与β辐射具有良好的线性关系。对动力学参数、灵敏度和剂量测定特性进行了评估。通过 TL 测量的可重复性实现了高精确度。

Thermoluminescence and Kinetic Parameters of Beta Rays Irradiated Egyptian Muscovite

The current work was going to study the dosimetric properties of Egyptian muscovite minerals irradiated with β-rays using the thermoluminescence technique (TL). The analysis of the TL glow curves was done using the (T_m − T_stop) and the initial rise methods. The deconvolution of the muscovite glow curves was analyzed to have eight superimposed trapping peaks. These trapes were located at 0.72, 0.80, 0.98, 1.09, 1.19, 1.30, 1.50, and 1.59 eV. Muscovite samples were studied at doses up to 330 Gy and exhibited good linearity in relation to beta radiation. The kinetic parameters, sensitivity, and dosimetric characteristics were evaluated. High accuracy was achieved through the repeatability of TL measurements.

期刊介绍： Luminescence provides a forum for the publication of original scientific papers, short communications, technical notes and reviews on fundamental and applied aspects of all forms of luminescence, including bioluminescence, chemiluminescence, electrochemiluminescence, sonoluminescence, triboluminescence, fluorescence, time-resolved fluorescence and phosphorescence. Luminescence publishes papers on assays and analytical methods, instrumentation, mechanistic and synthetic studies, basic biology and chemistry. Luminescence also publishes details of forthcoming meetings, information on new products, and book reviews. A special feature of the Journal is surveys of the recent literature on selected topics in luminescence.
