Occupational exposure

https://pubmed.ncbi.nlm.nih.gov/18512243/ "A new electromagnetic exposure metric: high frequency voltage transients associated with increased cancer incidence in teachers in a California school" "Abstract Background: In 2003 the teachers at La Quinta, California middle school complained that they had more cancers than would be expected. A consultant for the school district denied that there was a problem. Objectives: To investigate the cancer incidence in the teachers, and its cause. Method: We conducted a retrospective study of cancer incidence in the teachers' cohort in relationship to the school's electrical environment. Results: Sixteen school teachers in a cohort of 137 teachers hired in 1988 through 2005 were diagnosed with 18 cancers. The observed to expected (O/E) risk ratio for all cancers was 2.78 (P = 0.000098), while the O/E risk ratio for malignant melanoma was 9.8 (P = 0.0008). Thyroid cancer had a risk ratio of 13.3 (P = 0.0098), and uterine cancer had a risk ratio of 9.2 (P = 0.019). Sixty Hertz magnetic fields showed no association with cancer incidence. A new exposure metric, high frequency voltage transients, did show a positive correlation to cancer incidence. A cohort cancer incidence analysis of the teacher population showed a positive trend (P = 7.1 x 10(-10)) of increasing cancer risk with increasing cumulative exposure to high frequency voltage transients on the classroom's electrical wiring measured with a Graham/Stetzer (G/S) meter. The attributable risk of cancer associated with this exposure was 64%. A single year of employment at this school increased a teacher's cancer risk by 21%. Conclusion: The cancer incidence in the teachers at this school is unusually high and is strongly associated with high frequency voltage transients, which may be a universal carcinogen, similar to ionizing radiation."

I am a retired integrative medicine physician. After board certifications in Internal Medicine and Anesthesia and two decades of practice in Anesthesia, I went into Integrative Medicine to recover my own health and to help address the root causes of the increasing burden of chronic diseases. Thank you for this opportunity to comment. Most regulatory agencies have betrayed the public trust (and our health) by failing to adhere to the Precautionary Principle. Industry has been allowed to proceed without providing evidence of safety. There are over 1000 studies on the harms of Electro Magnetic Fields, the abstracts of which are catelogued by Green Med Info at https://greenmedinfo.com/problematic-action/electromagnetic-field-harms?utm_source=substack&utm_medium=email AND yet, the FCC continues to ignore a 2021 court order to update its Electromagnetic Field safety studies. Meanwhile, rollout continues on 5G, 6G, satellite, IoT, smart meters cell towers, and other sources of EMF exposure. The peer-reviewed record on 5G, 6G, satellite, IoT and smart-meter exposures is not adequate for safety assessment (Simkó & Mattsson, Int J Environ Res Public Health 2019, https://pubmed.ncbi.nlm.nih.gov/31540320/, concluded available studies "do not provide adequate and sufficient information for a meaningful safety assessment"). This is a gap. This is definitely not reassurance!(https://pubmed.ncbi.nlm.nih.gov/34047144/; https://pubmed.ncbi.nlm.nih.gov/34243228/); Balmori, Sci Total Environ 2015 (https://pubmed.ncbi.nlm.nih.gov/25747364/). Since the HHS, through the FDA is the agency that is positioned to supply the health-science information that the court found missing, I ask for a federal evidence review that holds agencies and industry to the Precautionary Principle.

They put a new cell tower up by my office. I’ve noticed I’ve started getting headaches and brain fog more and more. Something I use to never get. I’ve also noticed arthritis in my hands, especially when I use my cell phone. Unfortunately my office does have a WiFi box right under my desk so that does not help matters. Everyday I can’t wait to clock out just so I can go home turn all the lights out and lay down. I know it’s the insane amount of emf I’m exploded to while working because on weekends and when I’m on vacation I do not experience this.

I submit anonymously having been so harassed for speaking out about my wireless experience. But if the HHS wants to know more I am willing! 1. & 2. I responding as: an individual 3a. Wireless or RF/EMF sources: Homebound/off-grid in many locations since 2013--the worst is I can NOT get away from military communications. When military in on alert I know! Source unknown--PAVE PAWS, satellites, or cell towers? 3b. Nature: I unknowingly suffered from EMFs/wireless since working at a satellite focused company in Silicon Valley in the 80s. It didn't know the source of harm until temporarily paralyzed by an electric company "smart" meter in 2011. 3c. Adverse health effects: PAIN, paralysis, extreme exhaustion, neurological instability affecting everything in my body--all 5 senses, brain-fog, hormones, skin eruptions/bleeding, chemical/fragrance sensitivity, inability to detox, etc. 3d. Time from first exposure to adverse health effects: Unknown as I was unaware EMFs/wireless were triggering problems. 3e. Was medical evaluation or treatment sought? Continually sought, but MDs didn't have a clue so called it autoimmune. I sought out a formal diagnosis of sometime around 2020 after an EMR friend was put into mental incarceration for having slept with her electricity turned off. 3f. Steps taken to reduce exposure? Everything I could do to improve my health, moving off-grid, experts, shielding, finding better locations only to be followed by new wireless sources--living homebound--no one allowed on my property with cell phones, etc. Most everything I tried helped, but was followed by higher levels of far off frequencies. I had a spectrum analyzer which helped with analysis. 3g. Any supporting documentation? In 2011 I knew nothing about wireless until temporarily paralyzed by an electric company "smart" meter. I became an anti-wireless activist and learned military documentation back to 1930s showed harm, and thousands and thousands of credible studies show ill health effects! Additional Details: I witness people having a nice conversation, then I microwaves turning up, and then people suddenly disagree and turn on each other. I believe wireless is THE biggest problem in all physical and emotional health. If nothing else It simply prevents healing! B1a. Sources causing Adverse Effects: All wireless (and electricity > 1 mG) including cell towers, wireless phones, aircraft, home surveillance systems, car fobs, garage door openers, tracking devices (including “smart” meters, health implants, watches, cars, cameras, tools, pet collars...), microwave ovens, computers (printers, routers, wireless keyboards, mice...), wireless entertainment/speakers/headsets, scanners, power lines, refrigerators, electrical wiring, and most LED and florescent lights. B1b. Sources you can sense, but don't seem to harm you:- B1c. Sources you can use without sensing or being harmed:With improved health I appear to tolerate EMFs < 1 mG, and flashlights and small batteries without harm. B1d. Sources of benefit (i.e., electrotherapy): Electro-acupuncture initially harmed me, but appeared to be a lasting benefit. B2a. Health conditions contributing to EMF sensitivity including wireless: Great health before illness developed in the 80s while (in hindsight) working in a high EMF office located across the street from the GOES satellite being built/tested. Decades later realizing all symptoms triggered by EMF/wireless. B2b. Health conditions you don't necessarily associate with EMFs: EMFs/wireless harms my nervous system, ability to detox, and sleep. So I ALL of my conditions are rooted in EMFs/wireless harm. B3a. Helped tolerate exposure: Living off-grid away from all forms of wireless. A toxin-free environment (air, home, workplace, pets, and visitors.) Organic 4-day rotational diet with a high variety of foods, and quality water. Drugs/supplements free of additives, dyes, coloring, etc.(LDN, NAC, DIM, electrolytes & minerals, and maybe ivermectin most helpful.) Acupuncture done in an area of low EMF/wireless. XL Band by EMFSol.com gave me the ability to detox. Anything promoting detox – NAC, sweating, baths to draw out the toxins (so might include baking soda, salt, hydrogen peroxide, etc.). Meditation, but wireless prevents deep meditation. B3b. You recommend, but not positive helped: 0 B3c. Don’t recommend: Electrode therapy calmed my mind but lowered my state of health. B3d: Treatments no effect: Virtually all such as years of psychiatry for random onsets of anxiety only to discover it was triggered by airplanes flying overhead! B3e. Treatments made worse: Anything electrical such as EKG. Every doctor suggested drug. B4. Age range? 65-74 B5. What year become aware of sensitivity to EMF/wireless? Slightly aware late 1980s when felt pain sitting next to a neon light. 2011 is when temporarily paralyzed by a "smart" meter woke me up. B6. Where living when you first noticed EMF/wireless sensitivity? "Silicon Valley", CA

I am a concerned citizen who believes common sense should dictate research on every new installment of wifi towers,surveillance systems in schools,working environments and shopping establishment s.Its getting over utilized and we don't know how much electromagnetic exposure will effect us short term much less long term.Its COMMON SENSE to study the exposure. Stop putting profits before people. Thank-you.

I have been getting headaches and nausea at certain areas where I work. Since I work near a 5G tower, I purchased a Trifield EMF meter and sure enough, the places where I have been experiencing shooting head aches and nausea have been the places where the meter is screaming with the highest levels reaching even maximum range for the meter at times. This is in Raleigh NC on Capital Blvd.

HHS RFI — Reported Health Effects and Research Gaps I request that HHS investigate potential biophysical interactions between RF exposure and passive metallic implants. I have two titanium neck implants measuring approximately 6 cm and 7 cm, work in direct line of sight of a telecommunications tower, and have developed new cardiovascular and neurological symptoms. Kranold et al. (2025) identify implant-related electromagnetic dosimetry as a neglected safety issue, raising concerns about whether current exposure guidelines adequately protect people with implants. I have been unable to locate a physician qualified to evaluate this specific concern. I urge HHS to identify this as a clinical and research gap and facilitate independent scientific investigation under real-world RF exposure conditions.

I have developed a persistent cough since I work in Phoenix, Maryland in the last 4 years. At times I have unexplained headaches and am a healthy person. I have had to be on various medicine without explanation what’s going on with my lungs and do think it’s related to the numerous towers with the 5G and 6G surrounding our office in the Manor Shopping Center there is 6 total. The shopping center is owned by a lawyer named Tritt Farley, I will be vacating my space intent in end of November unfortunately to not work near them. Manor Shopping Center 3421 Sweet Air Road Phoenix, Maryland 21131 Please research and it’s a wonderful area to test unfortunately next door immediately is Jacksonville elementary school. Hope it’s not affecting the kids Gratefully, Deborah Campbell

Please look at the us army 1940-1955 medical command as well as field manuals discussion of the effects of known radio frequency at 1000 mhz and lower affect on white blood cell counts. As well as other health effects. The information is available and the microwave signal strength. The FCA is a commercial congressional committee that has ignored the medical data provided by the us military after the wwii era and the us army effects on soldiers of ionizing and radio frequency transmission and microwave radiation. Included is the Cold War veterans in in 1968 Germany following the invasion of the Czech Republic. All of which was declassified in 2012. The data is in the hands of the us government. It is your agencies responsibility to collect it. And this comment is notice.

I am a retired RN from California. I had exposures to cell phones, wifi, and electronic devices on the job. I have exposures to cell phones, cell phone towers, wifi and power lines in my personal life. I had exposure to smart meters, which, when implemented coincided with neurological symptoms. After opting out of the smart meter installation and going back to an analog electric meter, the neurological symptoms ceased. Scarato, T. (2025).
