The commenter calls for much lower RF limits, precautionary siting rules, public disclosure, wired school…

I am an informed citizen and parent. I request that federal agencies dramatically lower current exposure limits, adopt a rigorous and enforceable precautionary principle, and fund long-term independent research. Current limits are dangerously outdated and ignore exponential exposure growth. FCC/ICNIRP limits were set in the 1990s based on a single acute thermal model, for a world with a handful of cell towers and no Wi-Fi, no smart meters, no small cells, no 5G. That world no longer exists. The ambient RF environment has not merely grown -- it has multiplied. RF levels in Los Angeles were found to be 70 times higher than the EPA's own estimate from four decades earlier. Small cell deployment alone increases downlink RF emissions by a factor of 7 to 46. Bandara & Carpenter (Lancet Planetary Health, 2018) documented "planetary electromagnetic pollution" -- an unprecedented, compounding increase, with 68% of 2,266 reviewed studies showing significant biological effects. 5G densification makes this worse: millimeter waves require an order-of-magnitude increase in antenna density, placing transmitters at street level, in front of homes, schools, and hospitals. The public is being subjected to a massive, unconsented experiment in cumulative RF exposure, and the regulatory framework has not been updated. ICBE-EMF, Environ Health 21:92 (2022): current limits are based on invalid assumptions. Melnick et al., Environ Health (2026): applying EPA's own methodology, limits are at least 200x too high for cancer risk and 8-24x too high for male reproductive toxicity. The precautionary principle must be applied -- not merely acknowledged. The precautionary principle is codified in the Rio Declaration (Principle 15), the EU Treaty (Art. 191), and the Convention on Biological Diversity. Where there are threats of serious harm, lack of full scientific certainty shall not be used to postpone preventive measures. In the U.S., it has been systematically ignored in RF policy. FCC limits are set at the level of thermal injury -- the highest measurable effect -- rather than at a level that protects against non-thermal, chronic, or cumulative effects. This is a permissive threshold, not a protective one. I call on HHS to: Formally adopt the precautionary principle and ALARA standard in all RF policy; Establish interim precautionary limits at least 10-100x below current values for homes, schools, hospitals, nurseries (consistent with Council of Europe Resolution 1815/2011, which recommends 0.2 V/m -- roughly 1/100th of the current U.S. limit); Prohibit RF transmitters within 300m of schools and hospitals until long-term safety is demonstrated; Mandate transparent public disclosure of RF parameters near residential areas. Inaction is not a neutral position. When a population faces a compounding, invisible, inescapable increase in a physical agent, the only ethical course is to reduce exposure now, while research proceeds. Biological effects below current limits are well documented. IARC/WHO (2013): RF classified "possibly carcinogenic" (Group 2B). NTP (2018): "Clear evidence" of malignant cardiac schwannomas in male rats; "some evidence" for gliomas. Lai & Levitt, Rev Environ Health 39(3) (2024): oxidative stress, DNA damage, blood-brain barrier disruption below FCC limits. Bandara & Carpenter (2018): 68% of 2,266 studies showed significant biological effects. Sensitive populations require stricter protection. Children, fetuses, the elderly, and workers must be evaluated separately. Developing tissues are more vulnerable, no cradle-to-grave studies exist. The precautionary principle demands the highest protection for those who cannot consent. Cumulative exposure is unaddressed. Current limits treat each source in isolation. In reality, a resident is simultaneously exposed to multiple towers, small cells, Wi-Fi, smart meters, and 5G infrastructure. HHS must evaluate cumulative, neighborhood-level exposure. Recommendations: (a) Fund a long-term independent federal research program with prenatal/pediatric cohorts, reproductive endpoints, blinded pathology, open data; (b) Issue immediate interim guidelines (wired connections in schools, RF-off zones in bedrooms); (c) Require transparent consumer and school disclosure of RF parameters; (d) Establish a precautionary review mechanism that automatically tightens limits when new evidence of harm emerges. The ambient RF environment has increased by orders of magnitude and will increase further with 5G/6G. Current limits were set for a world that no longer exists. The precautionary principle demands we reduce exposure now, while we learn. The burden of proof belongs to the technology, not to the public.
