Commprehensive Government Study of the Potential Health Effects of Electromagnetic Radiation and Wireless Technologies
To Whom It May Concern:
I am writing to respectfully request that the appropriate government health and public-safety agencies undertake, support, or commission a comprehensive, independent study of the potential long-term health effects of exposure to electromagnetic fields (EMF) and radiofrequency (RF) radiation from the many wireless technologies now used routinely by the public.
Wireless technology has become an integral part of everyday life, and people may be exposed to multiple sources simultaneously and for extended periods. These sources include, but are not limited to:
5G and other cellular networks and infrastructure
Cell phones and smartphones
Wi-Fi and wireless internet routers
Bluetooth devices
Wireless earbuds and headphones
Wearable wireless devices and smartwatches
Wireless home and office equipment
Cellular towers and small-cell installations
Other consumer and telecommunications RF-emitting devices
I recognize that there is substantial scientific research concerning RF and EMF exposure, and that regulatory agencies have established exposure limits based on currently available evidence. However, given the rapid expansion of wireless technologies and the increasing duration and complexity of everyday exposure, I believe it is appropriate for the government to periodically reassess the evidence using current technology, exposure patterns, and epidemiological data.
I respectfully request that any such study examine, among other issues:
Long-term population health effects of chronic exposure to RF and other relevant portions of the electromagnetic spectrum.
Cumulative and combined exposure, including simultaneous exposure from cellular networks, Wi-Fi, Bluetooth, phones, wireless earbuds, wearable devices, and other sources.
5G and newer wireless technologies, including whether differences in frequencies, modulation, signal characteristics, network architecture, and exposure patterns warrant additional research.
Cell-phone use, including long-term and heavy-use patterns and exposure associated with devices held close to the body or head.
Wireless earbuds and Bluetooth devices, particularly because some devices may be used for many hours each day and in close proximity to the head.
Children and adolescents, including whether developing bodies or patterns of lifelong exposure warrant separate study.
Potential neurological, cognitive, reproductive, developmental, cardiovascular, sleep-related, and other health outcomes, while distinguishing established evidence from preliminary or uncertain findings.
Cancer and other long-latency outcomes, including sufficiently long-term epidemiological follow-up to identify effects that may not become apparent for many years.
Individual susceptibility and exposure differences, including whether certain populations may experience different effects from comparable environmental exposures.
Real-world exposure levels, rather than relying solely on theoretical or laboratory conditions, including measurements of aggregate exposure in homes, schools, workplaces, public transportation, and other environments.
Adequacy of existing exposure standards, including whether current limits sufficiently account for chronic, low-level, cumulative, or simultaneous exposure from multiple technologies.
Independent scientific review, with appropriate disclosure of funding sources, conflicts of interest, methodologies, raw data where possible, and the full range of relevant peer-reviewed evidence.
I also request that the government make the findings of such research readily accessible to the public and clearly distinguish between findings that are well established, findings for which evidence remains mixed or uncertain, and questions requiring further investigation.
This request is not based on an assumption that wireless technologies are harmful. Rather, it is a request for continued, independent, evidence-based surveillance and research as exposure patterns and technologies evolve. Given the widespread use of wireless devices and the potentially large population affected by any long-term health consequences, continued monitoring and rigorous research appear to be an important public-health responsibility.
I respectfully ask that this request be forwarded to the appropriate federal and/or state agencies, scientific advisory bodies, and public-health authorities for consideration.
