To Whom It May Concern,
I am writing to submit formal documentation and a public health inquiry to the Department of Health and Human Services regarding the severe biological effects, clinical evaluation gaps, and health risks associated with localized radiofrequency (RF) radiation and non-ionizing electromagnetic field exposure.
As an individual directly experiencing debilitating physical symptoms that correlate with localized technical findings, I am urging DHHS and its public health agencies to address the growing need for clinical protocols, diagnostic standards, and safety guidance for patients presenting with unexplained internal RF emissions, chronic tissue irritation, and severe neurological distress.
1. Severe Physical and Dermatological Symptoms
Over the past several months, I have experienced acute and worsening physical distress that severely impacts my daily life and health:
Neurological and Radiating Pain: Severe, debilitating pain originating from the right hip and shooting down both legs (consistent with acute radiculopathy), alongside chronic tension and discomfort across specific cranial, skeletal, and joint coordinates.
Cutaneous and Tissue Sensations: Daily, persistent sensations of burning across the skin and deep tissue.
Dermatological and Nail Changes: Unexplained structural changes, including nails turning black and periodically detaching/falling off, occurring without physical trauma or injury.
Cognitive Decline: Significant cognitive fatigue, memory disruption, and a decline in neurological processing functions, severely impacting my professional capacity as a medical records auditor.
2. Technical Findings and Spectrum Correlations
A technical radio frequency (RF) assessment conducted utilizing a Spectrum Analyzer and frequency readers identified 10 distinct anatomical regions emitting anomalous continuous or pulsed electronic frequencies, including:
Right Hip Region: 222.43168 MHz (directly correlating with acute, radiating right leg pain).
Right TMJ (Jaw) Region: 301.25804 MHz.
Cranial/Occipital Regions: Frequencies ranging between 197.81 MHz and 206.19 MHz.
These measured frequencies fall within specialized spectrum bands associated with bio-telemetry, transponder telemetry, and localized wireless tracking capabilities.
3. Requests for DHHS Action and Guidance
Given the intersection of public health, non-ionizing radiation exposure, and patient safety, I respectfully request that the Department of Health and Human Services consider the following actions:
Clinical Diagnostic Standards: Issue guidance or support for medical providers on how to evaluate patients presenting with localized pain, persistent burning sensations, dermatological anomalies, and measurable radiofrequency emissions.
Public Health Research: Direct public health research bodies (such as the NIH or CDC) to study the chronic, localized biological impact of continuous or pulsed VHF/UHF band emissions on peripheral nerves, deep soft tissue, nails, and central nervous system pathways.
Inter-Agency Collaboration: Coordinate with the FDA and FCC to establish clear reporting mechanisms for individuals who have documented unauthorized sub-dermal devices or targeted electromagnetic exposure resulting in severe physical harm.
Thank you for your time, dedication to public health, and consideration of these critical safety and medical inquiries. I look forward to your acknowledgment and response.
Sincerely,
Sandra Williams

Re: RF/EMF Exposure and Human Health: Response to Request for Information
Docket No.: HHS-OASH-2026-0397
Dear Sir or Madam,
Please find attached my submission, RF/EMF Exposure and Human Health: Response to the Request for Information, submitted on behalf of the EM Radiation Research Trust.
The submission draws on my personal experience, concerns raised by affected communities, scientific literature, and many years of research, public engagement and campaigning on radiofrequency electromagnetic fields (RF/EMF) and human health. It highlights concerns regarding the assessment of health risks associated with RF/EMF exposure, the need for independent research and transparent evaluation of the evidence, and the importance of meaningful public engagement in decisions affecting public health.
I am also providing the ECOLOG report (2000) concerning mobile telecommunications and health effects as a supplementary PDF for HHS to consider alongside my submission. Both documents contain references to scientific studies and relevant literature concerning RF/EMF exposure and human health. I respectfully urge HHS to examine these references and consider the research and evidence presented in both documents as part of its review.
In light of the serious public health concerns raised and the continuing scientific debate surrounding RF/EMF exposure, I urge HHS to give urgent consideration to the precautionary principle and implement appropriate measures to protect public health. Action to reduce avoidable exposure should not be unnecessarily delayed while further independent research and transparent scientific assessment continue. Protecting the public must remain a priority, with particular attention to potentially vulnerable groups, including children.
I respectfully request that both documents, together with the scientific references they contain, be considered as part of the HHS review and included in the relevant public record, in accordance with the applicable submission procedures.
Thank you for the opportunity to contribute to this important public health matter. I hope these materials will assist HHS in its consideration of the scientific evidence, the concerns of affected communities, and the urgent need for effective, transparent and precautionary measures to safeguard public health.
Yours faithfully,
Eileen O’Connor
