核动力反应堆一回路16N的泄漏率L可借助放置在二回路高压蒸气钢管道旁的γ射线探测器测量6.13和7.12MeVγ射线的计数率N得到。在一回路水中,氧受快中子照射的反应产物16N是半寿命T1/2=7.13s、衰变常数λ=0.0972的β衰变核。16N的两个激发态退激将放射出概率为68%的6.13MeV和5% The leakage rate L of the nuclear power plant primary circuit 16N can be obtained by measuring the count rates N of 6.13 and 7.12 MeV gamma rays with the help of a gamma ray detector placed beside the high pressure steam steel pipe of the second circuit. In the first-loop water, the reaction product 16N of oxygen irradiated by fast neutrons is β-decay nucleus with half-life T1 / 2 = 7.13s and decay constant λ = 0.0972. The two 16N excited state excursions will emit 6.13MeV with a 68% probability and 5%
