Investigation And Evaluation Of Electromagnetic Radiation Distribution In Suzhou Industrial Park

Electromagnetic radiation generally exists in the natural environment.With the rapid development of social economy and technology,the demand for electricity and communication equipment is increasing every day.The electromagnetic radiation pollution has become a new environmental problem.In order to grasp the present situation of the electromagnetic environment quality in Suzhou Industrial Park,so as to carry out relevant environmental management work more scientifically and effectively,and to ensure environmental safety,we hereby put forward the research of this subject.The main contents of this paper include: regional electromagnetic radiation environmental quality investigation and assessment,the main pollution sources surrounding electromagnetic environment quality investigation and assessment,electromagnetic environmental capacity calculation and give suggestions of the electromagnetic radiation environmental management.Based on the comprehensive survey of the Suzhou Industrial Park in the electromagnetic environment monitoring situation,combined with the characteristics of the electromagnetic radiation pollution source,to collect census monitoring data of 2011,2014,and 2015,to use Surfer statistical analysis software and contour drawing method,comparison analysis method,chart analysis method ect.to conduct the investigation and assessment of regional electromagnetic environmental quality and the main pollution sources surrounding electromagnetic environment quality,to analyze the spatial distribution characteristics,regularity and development trends,to use mathematical model to estimate the electromagnetic environment capacity of the SIP.The results show that the Suzhou Industrial Park,electromagnetic radiation power density,electric field strength,magnetic induction intensity are all in standard range and at a low level,the regional environmental quality electromagnetic background values satisfy the requirements of environmental protection.The isoline map shows that the electromagnetic radiation power density,power frequency electric field intensity and power frequency magnetic induction intensity are not uniform.Compared with the 2011,in 2014 the electromagnetic radiation power density and the frequency field intensity contours of the regional environment increased as a whole,and the intensive area expanded.The power frequency magnetic induction intensity is close to the whole,and the location of isoline density is changed.The power frequency electric field intensity and power frequency magnetic induction intensity of the 32 substations and 7 sets of overhead transmission lines in the SIP are in line with the relevant standard limit requirements.The power density of the environment around the mobile communication base station meets the relevant standard limit requirements.According to the research results,combined with the situation of SIP,this paper suggests countermeasures to prevent electromagnetic radiation,including further improve environmental planning,guaranteeing the development of electromagnetic environment safety,strengthening propaganda and education,raising awareness of electromagnetic environment protection of citizens,and strengthening the electromagnetic environment monitoring,etc.
