HHS-OASH-2026-0397-6377 https://www.regulations.gov/comment/HHS-OASH-2026-0397-6377 As Chief Scientific Officer of Children’s Health Defense, I urge the Department of Health and Human Services (HHS) to prioritize independent, transparent research into the biological and health effects of wireless radiation. As wireless infrastructure expands, we must address critical gaps in scientific understanding, reevaluate outdated federal exposure guidelines, and investigate potential risks to children and other vulnerable populations. Protecting public health requires rigorous science, transparency, and a commitment to following the evidence wherever it leads.
