Monitoring And Analysis Of Environmental Electromagnetic Radiation In Harbin

The electromagnetic radiation is the fourth environmental pollution source behind water, noise, atmosphere, Along with people applying electromagnetic technique extensively, the problem of electromagnetism pollution is gradually serious. Taking Harbin City as an example, the city area quality condition of general radiafrequency environment and specific source environment are introduced.For general radiafrequency environment, through a lattice stationing and monitoring, carry on the environment quality evaluation according to national standard to, and apply software of geographic information system Arc View GIS to draw the contour chart, as a result, more sanitary condition of general radiafrequency environment is mastered in the city area; at the same time, carry on concrete analysis by the way of adopting the pollution source inquisition to region of high the electromagnetism radiation level, and discover there is the medium wave transmitting tower in district, strengthen protection of electromagnetic radiation.To the specific source environment, through statistical analysis of electromagnetic radiation source first, mobilephone station and broadcast television system and high-tension system, are made main subjects investigated. The main method is the related standard with the electromagnetism environment monitoring, carry on the environment monitoring and analysis to three types of electromagnetic radiation source, the conclusion is that electromagnetic radiation is clean comparatively in their milieu environment; simultaneously, analyze aspects, such as proper characteristics of each kind of electromagnetic radiation source and the electromagnetism environment characteristics...etc., put the rationality suggestion on the programming and construction of the electromagnetic radiation source.For supporting the public health and preventing from the electromagnetism radiation pollution, it is a must to take potent prophylactico-therapeutic measures, suggest completing this work from strict carrying out policy laws, reasonable application the pollution control technology and strengthen the individual protection three aspects.Through research on the general radiafrequency environment and specific source environment in Harbin City, master the electromagnetic radiation level of the whole city district, it has a certain meanings of the theories and practice: systematize ror researching the contents; indicate a direction for scientific programming of electromagnetic radiator and prevention of pollution of the electromagnetic radiation; it is foundation for environmental management of electromagnetic radiation in future; provide a feasibility criterion for the investigation of electromagnetism pollution in other cities.
