Dosimetry is a technique that quantitatively measures the ionizing radiation absorbed by matter. The present study was conducted on the barites from a mine at Dongargaon in Central India. Morphological and structural analysis of proposed sample was carried out using X‐ray diffraction and standard error of the mean. Thermal analysis and chemical composition of the proposed sample were carried out using thermogravimetric analysis and differential thermal analysis, and electron probe microanalysis. Thermoluminescence (TL) studies on a natural barite sample were performed using a Nucleonix TL1009I TL reader following sample irradiation with γ‐rays generated from a ⁶⁰Co irradiation source. A broad TL glow curve was observed after TL study that was then deconvoluted using TLanal deconvolution software. Trapping parameters from the sample such as activation energy (E), order of kinetics (b), and frequency factor (s) were calculated using Chen’s peak shape method, the initial rise method, and Ilich’s method. The results indicated that the natural barite sample could be used in high‐dose TL dosimetric applications in various fields.

印度东加冈矿的天然重晶石样品的热致发光响应和俘获参数的研究

剂量测定是一种定量测量物质吸收的电离辐射的技术。本研究是对印度中部Dongargaon某矿的重晶石进行的。建议的样品的形态和结构分析使用X射线衍射和平均值标准误差进行。使用热重分析和差示热分析，以及电子探针显微分析，对拟议样品进行了热分析和化学成分分析。天然重晶石样品的热致发光（TL）研究是使用Nucleonix TL1009I TL读取器进行的，该样品用^60年代产生的γ射线照射钴辐射源。TL研究后观察到宽广的TL发光曲线，然后使用TLanal解卷积软件对其进行了反卷积。使用Chen的峰形方法，初始上升方法和Ilich方法，计算了样品的诱捕参数，例如活化能（E），动力学阶数（b）和频率因子（s）。结果表明，天然重晶石样品可用于各种领域的大剂量TL剂量学应用。
