辐射环境监测优化布点的特征分析方法

Optimal Number of Sites of Radiological Environmental Monitoring Based on Characteristic Analysis

介绍了特征分析方法的基本原理及其MATLAB语言实现过程,并将特征分析法、传统布点法,以及BP人工神经网络法对同一地区辐射环境监测优化布点的核素含量均值作了比较,结果表明,用特征分析法优选出的采样点位,其核素含量均值对传统布点法的相对偏差均为负值,且<10%,即便与BP法相比,也不失其优越性,表明用特征分析法监测一个地区环境辐射平均水平的优化布点是十分理想的。

This paper introduced a new way-characteristic analysis with its basic principle and the steps of building its MATLAB program. Moreover, the characteristic analysis was compared with others measures, such as traditional sites and BP NN in the field of environmental radiation monitoring. The results of application examples suggested that it was feasible to optimize number of sites for monitoring the average level of environmental radiation in one area by characteristic analysis.
