Application of Risk-Oriented Approach for Improvement of the Environmental Security of the Urban Area

Abstract

Improved comfort of urban environment is inseparably related with consumption and transfer of various types of energy for illumination and heating of buildings, provision of radio and TV broadcasts, mobile communications and transport. Energy transfer is accompanied by generation of electric fields, which propagate in ambient environment and affect human and biota. In this regard, the safety of urban environment becomes more and more urgent issue, especially along highways. This work describes a risk-oriented approach to analysis and estimation of risks of electromagnetic safety of urban territories with consideration for combined action of electromagnetic fields of various frequency range on humans. The authors have analyzed electromagnetic pollution from three most common sources of exposure, and the territories of urban environment have been selected with the highest level of electromagnetic hazard for population. Application of risk-oriented approach to estimation of electromagnetic hazard demonstrates the necessity of improvement of valid normalization system with accounting for simultaneous impact of electromagnetic fields from several sources on human and environment, which would provide development of more efficient measures of city population protection against this negative factor.
