在锕系元素的放化分离与分析工作中,需在质与量上精确测定U、Np、Pu、Am等α放射性核素。用于固态检测器的高分辨率α能谱测量是分析α放射性核素的基准方法。α能谱分析要求源测量薄而均匀,以减少α粒子的自吸收。电沉积法的技术简单可行,沉积率接近100%,所制备的源 In the actinide radiochemical separation and analysis work, the need for precise determination of quality and quantity of U, Np, Pu, Am and other α-radionuclide. High-resolution alpha spectrometry measurements for solid state detectors are the baseline method for analyzing alpha-radionuclides. The alpha spectrum analysis requires thin and uniform source measurements to reduce the self-absorption of alpha particles. Electrodeposition technology is simple and feasible, the deposition rate of nearly 100%, the preparation of the source
