Passive Detection of HEU Age

China Academy of Engineering Physics, Mianyang 621900, Sichuan, China; 

摘要: 利用HPGe-γ谱仪测量了多个年龄段的HEU样品，获得了样品中N(²¹⁴Bi)/N(²³⁴U)的值，从而计算得到了HEU的年龄，其测量结果与参考值吻合较好。最后结合实验结果，系统分析了其它可能用于测量高浓铀年龄的方法，并对各种方法的可行性进行了分析。结果表明， ²¹⁴Bi/²³⁴U比值法是最佳的选择。N(²³¹Pa)/N(²³⁵U)法中对γ谱如何解谱还需作进一步研究。 The HEU sample was measured by HPGe- γ spectrometry. By analyzing the detected γspectrum， the N(²¹⁴Bi)/N(²³⁴U) of the HEU sample was acquired, and the age of HEU samples was determined， which was coincided with the reference value. At last， the other potential methods of determining the age of HEU were analyzed systematically. N(²¹⁴Bi)/N(²³⁴U) is more feasible，and algorithm of spectrumdecomposition in N(²³¹Pa)/N(²³⁵U) should be studied further.
