HHS-OASH-2026-0397-5852 https://www.regulations.gov/comment/HHS-OASH-2026-0397-5852 With the proliferation of cell phone towers, smart meters, smart home devices, data centers and wireless devices in our environment, additional research needs to be conducted on the harmful effects of wi-fi, RF and EMF. As a concerned family member and caregiver, I believe human health experiences and clinical observations need to be taken into account. Exposure standards need to be reevaluated to limit human and animal exposure to wireless radiation and electromagnetic fields. Exposure measurement needs to be reevaluated in real-world situations, as humans use their cell phones by directly touching them and are often exposed to multiple sources of wi-fi simultaneously. Sensitive populations exposed to wi-fi, RF and EMF need to be studied such as children, pregnant women, the elderly, those who wear hearing aids with wi-fi or blue-tooth, those with implanted or wearable devices, workers with elevated exposure and those with preexisting conditions. It is imperative that existing scientific evidence be examined and additional research be conducted to study the adverse health effects of wi-fi, RF and EMF on humans and our environment. Please see attached studies. Thank you.
