HHS-OASH-2026-0397-5687 https://www.regulations.gov/comment/HHS-OASH-2026-0397-5687 I am submitting this comment to share concerns about potential EMF, RF, and wireless radiation exposure in Clinton, Maryland. Since approximately 2020, I have experienced persistent ringing in my ears, headaches, sinus-like symptoms, and unusual floor vibrations from unauthorized digging beneath my property that were not present previously. I have also documented what appear to be blue light rays and other unusual light phenomena directed toward my property and person, including video recordings captured at night. In addition, I have observed elevated EMF readings around certain nearby vehicles that remain stationary for extended periods. These observations have raised concerns about possible exposure from Wi-Fi systems, radio frequency transmissions, wireless infrastructure, and other electromagnetic sources. While I recognize that more research is needed, my experiences lead me to believe that potential health effects from long-term EMF and RF exposure deserve further scientific investigation. I encourage federal agencies to support independent research, review existing exposure standards, increase transparency regarding electromagnetic emissions in residential areas, and take public concerns seriously. Thank you for the opportunity to provide this input. Concerned American Clinton, Maryland
