旧城镇电磁辐射问题研究——以贵州兴义市为例

A Study of Electromagnetic Radiation in Old Towns——A Case Study of Guizhou,Xingyi

通过对贵州省兴义市旧城区电磁辐射的定点测量,得到了兴义市旧城区电场强度值。统计结果表明:兴义市旧城区的电磁辐射平均水平低于国标控制限值12 V/m,用SPSS软件分析显示电场强度数值符合正态分布,并基于此计算了兴义市旧城区电磁辐射超标的风险概率及电磁容量。结果表明:兴义市旧城区电磁辐射超标风险概率为0,可以无限制自由发展的时间为23 a。

The electric field intensity for the old urban area of Xingyi city was obtained through fixedpoint measurementof electromagnetic radiation.The statistical result shows theaverage electromagnetic radiation of the old urban areais lower than the GBcontrol standardof 12 V/m.The SPSS analysis revealsthat the distribution of the electric field intensity is in accordance with the normal distribution,and the risk probabilityof exceedingthe electromagnetic radiation standard and the electromagnetic capacity of the area are calculated on the basis of the analysis.The calculation indicates that the exceedance probabilityis 0 and the period of unlimited free development is about 23 years.
