ASSESSMENT OF THE ELECTROMAGNETIC FIELD OF MOBILE COMMUNICATIONS CELLULAR NETWORKS
Petar Ivanov, Galina Cherneva
Electromagnetic fields in the environment are constantly increasing as a result of increased use of various mobile devices, Wi-Fi routers, remote toys, etc. The expanding spectrum of personal, home, commercial and medical equipment significantly increases both the number of sources of electromagnetic fields and changes the levels and distribution of electromagnetic pollution.
According to Recommendation 1999/519/EC Council Recommendation on the limitation of exposure of the general public to electromagnetic fields (0 Hz to 300 GHz), ICNIRP GUIDELINES FOR LIMITING EXPOSURE TO TIME-VARYING ELECTRIC, MAGNETIC AND ELECTROMAGNETIC FIELDS (UP TO 300 GHZ) eight electrical, magnetic, electromagnetic and dosimetric dimensions are defined, which they usually use when measuring and assessing the electromagnetic field. Among them is the magnitude of the power density of the field. It is suitable and used to assess high-frequency electromagnetic fields when the depth of penetration of the field into the body is low.
The proposed report measures the power density of the electromagnetic field in a frequency range corresponding to mobile networks and services. The survey was carried out over a period of three days, at different time intervals and in a densely populated area. The resulting measurement data is processed and presented in tabular and graphical form using Microsoft Office Excel 2007 and Adobe Photoshop. The results are analyzed according to the norms according to national and international standards.
