HHS-OASH-2026-0397-2308 https://www.regulations.gov/comment/HHS-OASH-2026-0397-2308 The current human evidence does not establish that ordinary, limit-compliant exposure to 5G, Wi-Fi, cell towers, or smart meters causes cancer or other illness. This is not proof of zero risk. HHS should use reproducible evidence and measured exposure, not fear or anecdotes. A 2024 WHO-commissioned systematic review examined 63 epidemiologic articles from 22 countries. Mobile phone use was not associated with increased glioma risk (pooled relative risk 1.01; 95% CI 0.89–1.13), meningioma risk (0.92; 0.82–1.02), or acoustic neuroma risk (1.03; 0.85–1.24). The review also found no association between modeled exposure from fixed-site transmitters and childhood leukemia or pediatric brain tumors. A 2025 peer-reviewed UK field study measured RF emissions at 56 active 5G base stations across 30 publicly accessible locations. Worst-case estimates were at most 5% of ICNIRP 1998 public reference levels; 5G accounted for less than 10% of total measured RF exposure on average at those sites. HHS should maintain science-based, enforceable exposure limits; independently verify compliance; publish understandable measurements of actual exposure; and continue research into long-term exposure, higher-frequency 5G, children, and other understudied groups. Protect against established high-exposure hazards and study uncertainties. Do not portray compliant 5G, Wi-Fi, or smart meters as proven hazards without evidence.
