Like many other decorative building materials, tiles are one of the most precious ornamental ingredients for making a lucrative building image. It not only offers beauty and luxury but also added value by protecting/monitoring ionizing radiation. In this study, the utmost regular use of seven varieties of tile samples has been considered for retrospective thermoluminescence dosimetry. To observe the potentials of tiles for retrospective dosimetry, the major thermoluminescence properties (such as dose-response, energy dependence, self-sensitivity, relative sensitivity, glow curves, repeatability, fading, and also effective atomic number) has been investigated following the annealing - irradiation - readout cycles. Making an allowance for the various TL parameters, White Horse (Mirror Polish) tiles demonstrate suitability to be used as emergency TL dosimeter in 0.5-100 Gy dose array. Comparing the values of Z of these numerous tiles' samples (11.6-12.7) with TLD-200 (Z = 16.3), it is to be noted that tiles can be used as a suitable material for environmental radiation dosimetry. The thermoluminescent characteristics of tiles in the dose limit from 0.5 Gy to 100 Gy are reported here for the first time.
像许多其他的装饰建筑材料一样，瓷砖是制作高利润建筑形象的最珍贵的装饰成分之一。它不仅提供美观和奢华，还通过保护/监测电离辐射来增加价值。在这项研究中，考虑了七种瓷砖样品的最常规使用，以进行回顾性热释光剂量测定。为了观察瓷砖在回顾性剂量测定中的潜力，在退火-辐照-读取循环后，研究了主要的热释光特性（如剂量响应、能量依赖性、自敏性、相对灵敏度、发光曲线、重复性、退色以及有效原子数）。考虑到各种 TL 参数，白马（镜面抛光）瓷砖显示出在 0.5-100 Gy 剂量范围内作为应急 TL 剂量计使用的适用性。将这些大量瓷砖样品的 Z 值（11.6-12.7）与 TLD-200（Z = 16.3）进行比较，可以注意到瓷砖可以用作环境辐射剂量测定的合适材料。本文首次报道了瓷砖在 0.5 Gy 至 100 Gy 剂量范围内的热发光特性。
