Abstract

To overcome the time-resolution limitation inherent in the airflow-through scintillation cell method for radon measurement, this study introduces a compartmental model elucidating the behaviors of radon and its progeny within such cells. The computed results of the normalized equilibrium functions derived from the compartmental model, provide quantitative insights into the equilibrium progression of 222Rn and its progeny over time, substantiating the identified time-resolution limitation of 2-3 hours. Laboratory experiments confirm the efficacy of the proposed correction algorithm, showcasing its ability to surmount the time-resolution limitation and achieve a rapid response in radon measurement using airflow-through scintillation cells.

基于分区模型方法，利用气流通过闪烁池提高氡测量的时间分辨率。

为了克服气流通过闪烁池法测量氡固有的时间分辨率限制，本研究引入了一个区室模型，以阐明氡及其后代在这种池室内的行为。从分室模型中得出的归一化平衡函数的计算结果，为 222Rn 及其后代随时间的平衡进展提供了定量的见解，证实了所确定的 2-3 小时的时间分辨率限制。实验室实验证实了所建议的校正算法的有效性，展示了该算法在利用气流通过闪烁池进行氡测量时克服时间分辨率限制和实现快速响应的能力。

期刊介绍： Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
