Abstract

Abstract: Imaging plates can measure isotopes with alpha decay (such as radon and its progeny, americium, and so on). However, the detection efficiency of imaging plates is affected by alpha particle energy, types of imaging plates, and the overlapping effect. In this study, simulations were performed to analyze the relationship between detection efficiency and these three influence factors. The research findings suggest that BAS-TR and BAS-MS are well-suited for the detection of alpha particles with energy levels below 6.83 MeV and above, respectively. The track overlap effect correction method proposed in this study is applicable to both BAS-TR and BAS-MS image plates. The measurement results of radon progeny demonstrate that the correction method enhances the detection efficiency from 0.203 to 0.288. This study presents a valuable approach for selecting the appropriate image plate and correcting the track overlap effect in the measurement of alpha radioactive material concentration and other related information.

使用两种成像板检测阿尔法粒子的成像板检测效率研究。

摘要：成像板可以测量具有α衰变的同位素（如氡及其后代、镅等）。然而，成像板的探测效率受α粒子能量、成像板类型和重叠效应的影响。本研究对探测效率与这三个影响因素之间的关系进行了模拟分析。研究结果表明，BAS-TR 和 BAS-MS 分别非常适合检测能量水平低于 6.83 MeV 和高于 6.83 MeV 的阿尔法粒子。本研究提出的轨道重叠效应校正方法适用于 BAS-TR 和 BAS-MS 图像板。氡后代的测量结果表明，校正方法可将检测效率从 0.203 提高到 0.288。这项研究为在测量α放射性物质浓度和其他相关信息时选择合适的图像板和校正轨道重叠效应提供了一种有价值的方法。
