γ能谱解谱技术研究

Investigation of gamma spectra analysis

在核弹头的辐射指纹比较研究中,发现现在流行的γ能谱解谱软件有很多缺点,这些缺点直接影响到辐射指纹比对的准确性。鉴于此,本文设计了新的解谱程序。并对一些典型的模拟核弹头γ能谱,分别使用本程序、ORTEC公司的GAMMAVISION软件、CANBERRA公司的GENNIE2000软件进行解谱比较,以说明本研究工作在γ能谱解谱方面的一些成果。研究结果不但可用于涉及核弹头的核裁军核查研究中,而且可用于涉及放射性测量分析的各个领域。

During the comparative investigation of radiation fingerprint some current gamma spectrum analysis software are found to leave some drawbacks, which result in reduced precision of the radiation fingerprint comparison. We have therefore developed a new analysis software to solve the problem. In order to display the advantage of our program, some typical simulative warhead gamma spectra are analyzed by using our software and GAMMAVISION and GENNIE2000, respectively. The new software can be applied not only in nuclear warhead deep-cuts verification, but also in any radiation measurement field.
