Health disturbances and exposure to radiofrequency electromagnetic fields from mobile-phone base stations in French urban areas.

Abstract

The effects of radiofrequency exposure on the health of people living near mobile-phone base stations (MPBSs) have been the subject of several studies since the mid-2000s, with contradictory results. We aimed to investigate the association between measured exposure to radiofrequency electromagnetic fields (RF-EMF) from MPBSs and the presence of self-reported non-specific and insomnia-like symptoms. A cross-sectional survey conducted between 2015 and 2017 in five large cities in France involved 354 people living in buildings located at a distance of 250 m or less from an MPBS and in the main transmit beam of the antennas. Information on environmental concerns, anxiety, and non-specific and insomnia-like symptoms was collected with a questionnaire administrated by telephone. A complete broadband field-meter measurement [100 kHz - 6 GHz] was then made at five points of each dwelling, followed by a spectral analysis at the point of highest exposure, detailing the contribution of each service, including MPBS. The median exposure from MPBS was 0.27 V/m (0.44 V/m for global field), ranging from 0.03 V/m to 3.58 V/m, MPBSs being the main source of exposure for 64% of the dwellings. In this study population, the measured exposure from MPBSs was not associated with self-reported non-specific or insomnia-like symptoms. However, for insomnia-like symptoms, a significant interaction was found between RF-EMF exposure from MPBSs and environmental concerns. These findings do not support the hypothesis of an effect of RF-EMF from MPBSs on non-specific or insomnia-like symptoms in the overall population. Studies are needed to further investigate the positive association observed between exposure from MPBSs and insomnia-like symptoms among people reporting environmental concerns.

Main findings

In 354 residents living within 250 m of a mobile-phone base station, measured RF-EMF exposure from base stations (median 0.27 V/m; range 0.03–3.58 V/m) was not associated with self-reported non-specific or insomnia-like symptoms overall. For insomnia-like symptoms, a significant interaction was reported between base-station RF-EMF exposure and environmental concerns, and the authors note a positive association among those reporting environmental concerns.

Outcomes measured

• Self-reported non-specific symptoms
• Self-reported insomnia-like symptoms
• Environmental concerns
• Anxiety

Limitations

• Cross-sectional design (cannot establish temporality/causality)
• Symptoms were self-reported via telephone questionnaire
• Study restricted to residents within 250 m and in the main transmit beam; may limit generalizability

Suggested hubs

• who-icnirp (0.35)
  Observational study of health symptoms in relation to measured RF exposure from mobile-phone base stations, relevant to RF health-risk assessment discussions.
• 5g-policy (0.2)
  Base-station RF exposure and self-reported symptoms may be cited in policy debates about cellular infrastructure (though 5G is not explicitly mentioned).
