摘要
航空伽玛能谱测量是电离辐射环境评价中快速、经济、有效的方法,尤其在核事故应急中有重要的应用。本文详细报道了GR-820航空伽玛能谱仪对Cs人工源的全谱响应特征的实验结果,采用传统能量窗方137法和人工核素比值法对实验数据进行了处理,比较了这两种方法的有效性。本研究结果对核事故应急航空放射性测量方法和精细伽玛能谱全谱数据分解方法研究具有重要的意义。
Airborne gamma-ray spectrometry is a rapid, economic and efficient method for estimation of ionization radiation level, especially for nuclear accident investigation. The paper presents the spectra characteristics of full abstraction peak responding to 137Cs sources using airborne gamma-ray spectrometer (GR-820) in the experiment. The data were processed and have been interpreted by the energy band and ratio of VMMGC. We discussed the validity of these two methods. The results are of great significance for the research on airborne survey for nuclear emergency and spectral data deconvolution.
