Measurement and assessment of electromagnetic fields near radiophones in line with provisions of European Directive 2013/35/EU and Polish labour law
Abstract
Background: The activities of rescue and uniformed services require the use of wireless communication devices, such as portable radiophones. Assessment of workers' exposure to electromagnetic fields emitted by radiophones is important in view of occupational safety and health (OSH), legislation requirements and reports on possible adverse health effects in users of devices emitting radiofrequency electromagnetic field. Materials and Methods: In this study 50 portable radiophones of conventional and trunked communication systems were investigated. The assessment of electromagnetic hazards to users involved unperturbed electromagnetic field measurements near radiophones' antennas. Results: The electric field strength corresponding to the occupational exposure level (fields of so-called safety zones established by OSH legislation in Poland) was measured at a distance of 45-65 cm from the portable radiophones antennas of conventional system and 75-95 cm from antennas of trunked system radiophones, depending on their type and mode of work. The assessment was based on the averaged results of series of measurements. The electric field strength exceeding action levels defined by Directive 2013/35/EU was found up to 15 cm from radiophone antennas of conventional system and up to 10 cm from the antennas of trunked system radiophones. Conclusions: Taking into account the range of safety zones and the use of portable radiophones near the body, their users should be classified into the group of workers occupationally exposed to electromagnetic fields. Electromagnetic field measurement results and typical conditions of using portable radiophones justify theneed for additional assessment of electromagnetic hazards - the analysis of compliance with relevant exposure limit values provided by Directive 2013/35/EU.
