AI 中文摘要
纳米剂量学旨在提供与纳米级粒子径迹结构相关的可测量量，该结构决定了辐射的生物有效性。尽管模拟纳米剂量学已展现出在放射治疗计划中的潜力，但实用纳米剂量探测器的实验实现仍处于早期阶段。本研究开发了一种低压气体驱动的纳米剂量学原型，用于计数纳米等效灵敏气体体积内的电离事件；利用Am-241源的α束在1毫巴丙烷气体中对其性能进行实验评估，结果支持这类紧凑型纳米剂量计的进一步开发，其潜在应用涵盖粒子治疗、辐射防护及空间辐射剂量测量。
英文摘要
Nanodosimetry aims to provide measurable quantities related to the nanoscopic particle track structure, which determines the biological effectiveness of radiation. While simulated nanodosimetry has already demonstrated its potential for radiation treatment planning, the experimental realization of practical nanodosimetric detectors is still in its early stages. In this work, a nanodosimetric prototype operated with low-pressure gas was developed to count ionizations in a nanometer-equivalent sensitive gas volume. Its performance was evaluated experimentally with alpha beams from an Am-241 source in 1 mbar propane gas. The results support the further development of this compact nanodosimeter class, with potential applications in particle therapy, radiation protection, and space radiation dosimetry.
