1 JOURNAL OF RAILWAY ENGINEERING SOCIETY Aug 2013 NO. 8 Ser X5 A Research on the Environmental Impact Factors of Electromagnetic Radiation from High - speed Railway HUANG Dun China Railway Siyuan Survey and Design Group Co. Ltd Wuhan Hubei China Abstract Research purposes With the rapid development of high - speed railway electromagnetic radiation from high - speed railway has become widespread environmental concerns but its impact on the human body is inconclusive. So this paper carried out analysis and studied on environmental impact factors of electromagnetic radiation from high - speed railway. Research conclusions 1 Currently there are many global differences in research results conclusions and viewpoints on biological effects of electromagnetic radiation there are still uncertainties of the impact of electromagnetic radiation from high - speed railway on the human body which needs long - term and in - depth exploration and research. 2 In general electromagnetic radiation from Wuhan - Guangzhou Passenger Line does not constitute prominent environmental impact but taking into account the emotions of anxieties and worries of the people along the line to electromagnetic radiation the project construction company still makes its best efforts to take necessary protective measures to ensure that the health of residents around the sensitive facilities are not affected and the people along the line whose TV reception may be affected receive reasonable compensation. 3 The mitigation measures include base station location optimization housing function replacement and cost compensation etc. 4 The research results of this paper will provide a reference for environmental impact assessment EIA and preventive measures of the electromagnetic radiation from high - speed railway. Key words high - speed railway electromagnetic radiation environmental impact factors
