Abstract

The aim of retrospective dosimetry is to estimate absorbed radiation doses experienced by individuals or objects in past events using physical, chemical, biological, or historical evidence. Solid-state dosimetry techniques, such as thermoluminescence (TL) and optically stimulated luminescence (OSL), play a crucial role in reconstructing radiation exposure scenarios. In this study, the feasibility of using automotive spark plugs as retrospective dosimeters was investigated, inspired by the luminescent properties of the ceramic insulator, which is primarily composed of alumina (Al₂O₃). The high operational temperature of spark plugs effectively reset any pre-existing environmental radiation signals, ensuring that any luminescent response primarily reflects accidental radiation exposure. The single-aliquot regeneration-dose (SAR) protocol was applied using TL and OSL to assess the dosimetric properties of spark plug insulators. The results demonstrate that these components can serve as reliable dosimetric materials and can accurately map radiation dose distributions in accidental exposure scenarios.

使用火花塞陶瓷材料进行回顾性剂量测定。

回顾性剂量学的目的是利用物理、化学、生物或历史证据估计个人或物体在过去事件中所经历的吸收辐射剂量。固体剂量学技术，如热释光（TL）和光激发发光（OSL），在重建辐射暴露场景中起着至关重要的作用。在这项研究中，受陶瓷绝缘体（主要由氧化铝（Al2O3）组成）发光特性的启发，研究了将汽车火花塞用作回顾性剂量计的可行性。火花塞的高工作温度有效地重置任何预先存在的环境辐射信号，确保任何发光反应主要反映意外辐射暴露。采用单等分再生剂量法（SAR）对火花塞绝缘子的剂量学特性进行了TL和OSL评价。结果表明，这些组分可以作为可靠的剂量学材料，可以准确地绘制意外照射情景下的辐射剂量分布。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
