Spatial Distribution and Pollution Risk Analysis of Electromagnetic Radiation in Changchun City

Abstract

To evaluate the electromagnetic radiation pollution in Changchun City and determine the risk of pollution, the probability theory of extreme value distribution is used to build the computational model of electromagnetic pollution risk and discusses their property according to situation that the current urban growth of electromagnetic energy mainly comes from mobile base stations and radio frequency radiation sources. According to the integrated electric field intensity which monitored from Changchun City’s 442 monitoring station by electromagnetic environment monitoring station in Jilin Province, the risk of electromagnetic pollution in Changchun City probability is calculated, ordinary Kriging method is used to draw the map of Changchun City electromagnetic radiation field strength and calculates electromagnetic pollution risk probability. The result indicates that the electromagnetic environment is safe. The value of electric field strength in the office area is higher than other regions. The map drawing by fuzzy Kriging method is more accurately than the map drawing by ordinary Kriging method.
