The work dwells on finding solutions to a task related to substantiating locations where instrumental measurements should be performed within a program for monitoring over exposure to electromagnetic radiation (EMR) in radio-frequency range in a large industrial city with its area exceeding 800 km2 and population being more than 1 million.
A database has been created (and bound to a vector map of the city) containing data on 2 011 sources of EMR in radio-frequency range. They were 1 666 basic mobile communication stations; 248 units in radio-relay communication lines made of radio-relay station chains; 95 aerials belonging to three broadcasting centers; and 2 trace surveillance radar sets. Electromagnetic fields were calculated as per a regular grid in 109 thousand considering points at 22 heights ranging from 3 to 75 meters above the ground. When performing calculations, the authors took into account locations, height and number of floors of 31 949 buildings including 17 307 apartment blocks; 3 160 administrative buildings; 307 pre-school children facilities and 105 schools. Results obtained via spatial modeling of electromagnetic exposure were verified with selective instrumental measurements. Data were satisfactorily convergent. It was detected that local zones with maximum electromagnetic exposure in radio-frequency ranges occurred at 18-27 meters above the ground. Instrumental research proved there were high electromagnetic fields levels at such heights including those that were 1.03-5.79 times higher than maximum permissible levels. The authors gave grounds for locations where posts for instrumental measuring should be placed in order to perform monitoring over electromagnetic radiation in radio-frequency range; it was done taking into account population density for subsequent assessment of exposure and health risks. |
