Abstract

It is mandatory to review environmental radiofrequency electromagnetic field measurement protocols and exposure regulations: An opinion article Lopez I, Rivera M, Feliz N, Maestu C. It is mandatory to review environmental radiofrequency electromagnetic field measurement protocols and exposure regulations: An opinion article. Front. Public Health, 24 October 2022. Sec. Radiation and Health. doi: 10.3389/fpubh.2022.992645 No abstract Excerpts "According to the International Telecommunication Union (ITU) World Telecommunication/ICT Indicators Database in 2004 there were 1.76 billion mobile phone subscriptions in the world, in 2020 this figure increased to 8.27 billion (1). By 2023, there are expected to be 13.1 billion mobile terminals, almost 10% of which will be 5G technology (2)." "Several scientific studies evaluate the possible effects of prolonged exposure to microwaves at the epidemiological level (4–11) and in vitro or in vivo models (12–19). However, the use of different methodologies in radiation measurement processes and different configurations of exposure equipment, such as frequency, radiation power density, and exposure time; do not allow adequate comparison of results, which makes it difficult to draw conclusions." " Although most countries such as Spain, Germany, France or Finland adopt the limits proposed by the ICNIRP, the existing regulations in other are different, with limits more restrictive in countries such as Denmark, Bulgaria, Italy, Switzerland, China or Russia (21–23)." "Old standards and measurement methodologies are not adapted to the new communications standards and technologies" "Underestimation of non-thermal effects in the development of measurement methodologies" "Many researchers consider the choice of the SAR criterion as the only parameter for assessing effects on biological systems as insufficient, as it only takes into account the thermal effects resulting from exposure (48– 50). The ICNIRP guidelines state that a one Celsius degree increase in body temperature is the acceptable limit to avoid adverse health effects (20). Although a reduction factor of 50 is applied to the SAR value capable of increasing the temperature by 1°C, no account is taken of other effects not related to temperature increase. These effects, have been reported in numerous in vitro and in vivo studies to occur at lower intensities than those required to cause thermal effects by low and high frequency EMFs, such as alterations in gene expression (51, 52), oxidation processes (12, 14, 19, 53–56), the flow of calcium ions (57–59), proteins (60) or cell viability (13, 17)." "The studies assessing the possible effects of RF-EMFs in vitro should consider all important parameters in the exposure: intensity, frequency, modulation and time of exposure. The possible existence of bioactive windows in frequency, intensity or modulation, as well as the non-linear response of biological systems that could produce differences in cellular behavior should be considered in the development of measurement methodologies and the establishment of exposure limits and could serve as a precedent to establish mechanisms of action of these RF-EMFs in relation to biological systems." "In conclusion, two main ideas arise: the review of the environmental EMFs measurement protocols and the need for a comprehensive assessment of all the effects of EMFs not only thermal effects. Measurement protocols must identify the specific frequencies of each of the currently established major frequency bands, the temporal behavior of the signal and the power density. Measurement systems must not only determine averaged field strengths but must be able to measure the peak amplitude over time and, consequently, the cumulative radiation. This would make the characterization of EMFs much more realistic. In addition, parameters such as frequency and modulation could be important when considering potential biological effects. Choosing intensity as the only determining parameter for the occurrence of effects is a reductionist conception. The consideration of all EMFs parameters in the assessment of biological response should be mandatory." Open access paper: frontiersin.org

Main findings

Opinion article arguing that existing environmental RF-EMF measurement methodologies and exposure regulations are not well adapted to newer communication technologies and may not adequately capture relevant exposure characteristics (e.g., specific frequency bands, temporal behavior, peak amplitude, cumulative radiation). The authors state that relying on SAR/thermal criteria alone is insufficient and call for assessment frameworks that also consider other exposure parameters (e.g., frequency, modulation, intensity, time) and potential non-thermal effects reported in in vitro/in vivo studies.
