摘要

提出了一种利用 CR-39 塑料核轨道探测器中的轨道几何参数对α粒子进行光谱分析的方法。分析了轨道登记灵敏度与每个蚀刻坑入射角之间的关系。当蚀刻水平不超过 CR-39 的范围时，可大致分离出氡、钍和 241Am 所发射的阿尔法粒子的成分。这项工作旨在提高室内氡和钍照射剂量评估的准确性。

Spectroscopic analysis of alpha particles from radioactive nuclides with CR-39 plastic nuclear track detectors.

A spectroscopy method of alpha particles with the track geometry parameters in CR-39 plastic nuclear track detectors is proposed. The relationship between the track registration sensitivity and incident angle of each etch pit is analyzed. The components of alpha particles emitted from radon, thoron and 241Am can be roughly separated when the etching level is not exceeded beyond the range in CR-39. This work aims at improving the dose assessment accuracy from exposure to indoor radon and thoron.

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.
