航空伽玛射线全能谱数据分析方法的理论研究

摘要

Spectra of airborne gamma-ray spectrometry was found to be the synthesis of spectral components of radioelement sources by analyzing the constitution of radioactive sources for airborne gamma-ray spectrometric survey and establishing the models of gamma-ray measurement. The mathematical equation for analysising airborne gamma-ray full spectrometric data can be expressed into matrix and related expansions were developed for the mineral resources exploration, environmental radiaction measurement, nuclear emergency monitoring, and so on. Theoretical study showed that the atmospheric radon could be directly computed by airborne gamma-ray spectrometric data with full spectrum analysis without the use of the accessional upward-looking detectors.%通过航空伽玛能谱测量的源项分析和测量模型建立，发现航空伽玛能谱测量谱是各种源项能谱成分的合成谱。对航空伽玛射线全能谱分析方法给出了其数学分析式，其通用式可表示为矩阵式，对于矿产勘查和核环境与核应急等不同的应用领域能表达成相应的展开式。理论研究表明，航空伽玛全谱法不需要附加的上测探测器，就可直接解决大气氡修正问题，还将具有较好的经济效益。
