“…The level of exposure to RF-EMR is significantly lower than the general public exposure limit provided by international guidelines and legislation established in various countries (4-61 V/m) (Council Recommendation, 1999; Gryz et al, 2014a;Stam, 2011;ICNIRP, 1998). system switched-on, talk between engine-driver and traffic operator sensitivity of meter Although the total level of RF-EMR exposure in metro is comparable with typical scenarios existing in urban areas, the specific conditions of EMF radiation propagation inside the underground infrastructure (such as the underground location of tubes and stations -closed spaces rounded by walls), mean that specific character of this exposure needs attention when health hazards from exposure are discussed -in the context of frequency composition, spatial distribution and the ratio between electric and magnetic components (i.e.…”

“…Investigations involving this new technique of using exposimeters for assessing RF-EMR in various environments have been on-going in Poland since 2011, and have included a systematic study on the metrological properties of frequencyselective exposimeters, the relationship between the results of exposimetric investigations and unperturbed RF-EMR in the case of various ways of using exposimeters and exposure analysis in various environments (Gryz et al, 2012(Gryz et al, , 2014a(Gryz et al, ,b, 2015. Based on preliminary studies, RF-EMR exposure inside the underground metro infrastructure has been identified as an example of an environment where some specific parameters of exposure profile are expected.…”

Antennas from various wireless communications systems [e.g. mobile phones base transceiver stations (BTS) and handsets used by passengers, public Internet access, staff radiophone transmitters used between engine-drivers and traffic operators] emitting radiofrequency electromagnetic radiation (RF-EMR) are used inside underground metro public transportation. Frequency-selective exposimetric investigations of RF-EMR exposure inside the metro infrastructure in Warsaw (inside metro cars passing between stations and on platforms) were performed. The statistical parameters of exposure to the E-field were analyzed for each frequency range and for a total value (representing the wide-band result of measurements of complex exposure). The recorded exposimetric profiles showed the dominant RF-EMR sources: handsets and BTS of mobile communication systems (GSM 900 and UMTS 2100) and local wireless Internet access (WiFi 2G). Investigations showed that the GSM 900 system is the dominant source of exposure - BTS (incessantly active) on platforms, and handsets - used by passengers present nearby during the tube drive. The recorded E-field varies between sources (for BTS were: medians - 0.22 V/m and 75th percentile - 0.37 V/m; and for handsets: medians - 0.28 V/m and 75th percentile - 0.47 V/m). Maximum levels (peaks) of exposure recorded from mobile handsets exceeded 10 V/m (upper limit of used exposimeters). Broadband measurements of E-field, including the dominant signal emitted by staff radiophones (151 MHz), showed that the level of this exposure of engine-drivers does not exceed 2.5 V/m.

“…Z punktu widzenia bezpieczeństwa pracy istotne jest wskazanie urządzeń emitujących pole elektromagnetyczne o ekstremalnie niskiej częstotliwości (extremely low frequency -ELF) i o częstotliwości radiowej (radio frequency -RF). Urządzenia elektroenergetyczne to źródła pola o niskiej częstotliwości, a urządzenia telekomunikacyjne są źródłami pola o wysokiej częstotliwości [9,10]. Dopuszczalny poziom emisji pola EMF podlega ścisłym regulacjom prawnym, których celem jest zapewnienie bezpieczeństwa pracowników w miejscu pracy.…”

The current development of electric power industry in Poland, especially in the field of renewable energy sources, including wind power, brings about the need to introduce legislation on new work environment. The development of occupational safety and health (OSH) regulations that must be met by new workplaces, such as offshore substations becomes necessary in view of the construction of modern offshore wind power plants - offshore wind farms. Staying on offshore substation is associated with an increased exposure to harmful health factors: physical, chemical, biological and psychophysical. The main sources of health risks on offshore substations are: temperature, electromagnetic field, noise from operating wind turbines, direct and alternating current, chemicals, Legionella bacteria and social isolation of people. The aim of this article is to draw attention to the problem of offshore substation workers' exposure to harmful factors and to present methods of preventing and reducing the risk-related adverse health effects. In this paper, there are identified and described risks occurring on offshore substations (fire, explosion, lightning, accidents at work). Some examples of the means and the methods for reducing the negative impact of exposure on the human health are presented and discussed. The article also highlights the need to develop appropriate laws and health and safety regulations concerning the new working environment at the offshore substations. The review of researches and international standards shows that some of them can be introduced into the Polish labor market.

“…The biological consequences derive from the radiation conditions, such as the strength of the dose, way of fractioning, mass and type of tissues exposed to radiation, as well as their oxygenation. The effects of the exposure to radioactivity depends also on the individual biological characteristics of a body [5][6][7][8].…”

Introduction and objective. The male reproductive system constitutes a set of tissues which are particularly sensitive to external factors. The aim of the study was to analyze the relationship between background radioactivity and the quality of the semen of the men who have reported to the infertility treatment facility in 2000-2016 in the Lublin region of eastern Poland. Materials and method. The radioactivity of the ground-level air layer obtained from the Institute of Meteorology and Water Management in Włodawa in the Lublin region was analysed. 4,250 spermiograms of patients who reported to the treatment facility for the first time due to infertility were analysed and correlated to background radioactivity in the Lublin region in 2000-2016. Results. A long-term decrease in the percentage of morphologically normal spermatozoa of the patients was observed (r=-0.970; p<0.001 in 2000-2009 and r=-0.925; p=0.003 in 2010-2016). Men's age correlated negatively with sperm motility (r=-0.164; p=0.009) and morphology (r=-0.186; p=0.009). The percentage of spermatozoa with normal morphology was lowered by beta-isotopes of artificial origin in the air in 2000-2009 (r=-0.655; p=0.040) and by the exposure to gamma radiation of the ground-level atmosphere in 2010-2016 (r=-0.676; p=0.048). The percentage of sperm vitality was lowered by gamma radiation in the atmosphere (r=-0.636; p=0.006), but improved by beta isotopes in precipitation (r=0.686; p=0.002) in the whole of the analyzed period. Conclusions. The percentage of morphologically normal spermatozoa in patients who reported to the infertility treatment depends not only on the age of patient, but also on beta-isotopes of artificial origin and gamma radiation in the atmosphere. Beta isotopes in precipitation affect the improvement of sperm vitality.
