摘要： 基于辐射环境监测的实际工作，我们设计了一个基于α谱仪测定环境水样中铀同位素的本科专业实验。该实验包含铀的分离纯化、电镀制源、谱仪测量及数据分析三个部分。通过该实验，学生亲身体验了实际环境监测工作的流程，加深了对阿尔法谱仪的理解，提升了操作能力，促进了学生理论知识与实践经验的融合。

Abstract: Based on the practical work of radiation environmental monitoring, we have designed an undergraduate experiment to measure uranium isotopes in environmental water samples using alpha-spectroscopy. This experiment comprises three parts: uranium separation and purification, preparation of the electroplating source, and spectrometer measurement with data analysis. Through this experiment, students gain hands-on experience in the actual environmental monitoring process, deepen their understanding of alpha-spectrometers, enhance their operational skills, and promote the integration of theoretical knowledge with practical experience.
