Description
Introduction: Environmental and occupational radiofrequency electro magnetic safety problems are increasing by 5G networks introduction. The correct electromagnetic field (EMF) exposure assessment is one of this problem important aspect. The control methods enhancements suitable for new EMF frequency ranges, widespread radio channels, beamforming technology and cellular standards are crucial for this factor hygienic assessment system in Russia. 5G EMF exposure assessment pilot study was carried out in Moscow.
Materials and methods: The 5G new radio base stations operated in n79 band with 100 MHz channel bandwidth has been tested in Moscow 5G pilot zones. EMF exposure was assessed under beamforming mode, downlink transmission was implemented by data traffic to user equipment. EMF levels were measured by means of selective meter SRM 3006 (Narda Safety, Germany). The frequency selective measurements were carried out to control the radio channel and SSB power density levels. The data traffic was traced in time domain.
Results and conclusions: EMF levels in traffic beams varied from
0.79±0.18 to 7.08±1.42 W/cm2 depending on traffic speed and
measurement point. The evaluated exposure level was 1.01±1.42 W/
cm2 at the greatest observed distance from base station (~220 m). The
selective measurement results allow EMF exposure evaluating from
separate base station as well as the maximum possible new standard
contribution for general exposure estimation. The considered EMF
control methods are actual for hygienic practice at national and
international levels.
