Research and Apply with Peak Stabilization Technology

研究内嵌^(241)Amα源的NaI探测器在不同工作环境下,所测排放气体中的γ放射性核素能谱的漂移趋势,通过改变探测器的工作温度及工作电压等实验,探索所测能谱的漂移规律,并运用合适的软硬件电路来实现能谱的稳峰功能。这种稳峰技术确保了所测γ放射性核素的准确性及能谱的稳定性,使得在实际应用中能正确辨别γ放射性核素的类别,是详细分析各种放射性核素的排放浓度及排放置的前提。

This paper studies the drift trend of γ radionuelide spectrum of emissions gas by NaI detector embed- ded α radioactive source in different working conditions, changing the operating temperature and the operating voltage of the detector to explore the laws of the measured spectrum of the drift trend, and the using of appropri- ate software and hardware circuit to achieve the stability of the energy spectrum peaks. This teehnique can en- sure accuracy of the measured γ radionuelide and the stability of the energy spectrum peaks. So in practical ap plications the device can distinguish the γ radionuelide correctly and can perform detailed analysis of emission concentration.
