摘要
使用多线γ放射源、氯化钠热中子俘获γ射线源、￣（１９）Ｆ（ｐ，αγ）源以及镍热中子俘获γ源来得到全能峰、单逃逸峰和双逃逸峰在７００－９０００ｋｅＶ能区范围内探测器本征效率值随能量变化的曲线。所得结果用来确定镍热中子俘获γ场，￣（１９）Ｆ（ｐ，αγ）反应γ场及反应堆重水循环系统上￣（１６）Ｏ（ｎ，ｐ）￣（１６）Ｎ反应γ场的γ剂量，并将其与用电离室测试的结果进行比较。
Using multiline γ radiation source,thermal neutron capture γ rays of NaCl and ￣(19)F(p,αγ)re-action γ rays the intrinsic efficiencies of total energy, single escape and double escape peaks forhigh purity germanium detector are determined in the 700-9000 keV γ energy range. The mea-sured doses of nickel thermal neutron capture γ ray field,￣(19)F(p,αγ) reaction γ ray field and 6.13MeV γ ray field produced by ￣(16)O(n,p)￣(16)N reaction on the heavy water cyclic system of reactor arecompared with measured data ...
