These wireless transmitters typically operate at present between 800 Megahertz (MHz) and 5 Gigahertz GHz), with new devices now coming into use with the latest 5G technologies that are capable of operating between 2.4 and 95 GHz using very short wavelengths called millimeter waves. This comment is in response to the U.S. Department of Health and Human Services’ Request for Information on EMFs, RF and Wireless Radiation Exposure and its Impact on Health published in the Federal Register Vol 91, No 181 dated September 21, 2026.\n\nI have given expert testimony regarding the dangers of this type of radio frequency radiation (RFR) based on my background as an electrical engineer, biomedical engineer and medical doctor who has also completed also a post-doctoral fellowship in physiology and served as a Bioscience Officer in the Canadian Armed Forces. Details of my background and contact information can be found in the longer Word document attached to this comment.\n\nSince the 1996 Telecommunications Act that established the U.S. nation-wide cellular communications network, there have been essentially no new health protection standards implemented to protect the general population despite massive research studies showing evidence of harm to the general population. \n Especially problematic is Radio Frequency Radiation that comes from transmitters close to the body as well as high powered transmitters from cell towers and antennas, microwave transmitters covering schools, housing projects and apartment complexes where the transmitters are often hidden in ceilings and walls.  The Federal Communications Commission (FCC), which is charged with protecting the public, has exposure standards that are principally suitable for short-term exposure and only those that concern heating or thermal effects while ignoring any long-term exposure and non-thermal effects that are now the norm.\n\nThe widespread proliferation of this technology now in its 5th generation of development (5G), is viewed by hundreds of scientists throughout the world as hazardous to human welfare.  The United States has one of the highest exposure guidelines in the developed world which is hundreds of times higher than permitted in other countries including China, Eastern European countries and Russia which have studied the long-term health effects of these RF radiations and chosen to protect their populations appropriately.\n\nWe have known of the adverse health effects for at least five decades with thousands of studies demonstrating an increased incidence of brain tumors (gliomas, acoustic neuromas, glioblastomas and pituitary tumors) in addition to thyroid and parotid gland tumors.  Breast cancers have been demonstrated in young women exactly at the multiple antenna sites who carried their cell phones inside their bras.  The International Agency for Research on Cancer (IARC), a division of the World Health Organization (WHO), has classified electromagnetic radiation as a Class 2B possible carcinogen in 2011 based on numerous scientific studies.\n\nMy full comment and a brief summary of my past experience and qualifications are attached in the Word file attached as well as 2 PDFs of presentations that substantiate my concerns about the adverse health effects of long-term EMFs and the wireless radiation.  I am writing this comment both as a past expert, a healthcare provider, and a very concerned living man who has observed great suffering from many electrosensitive people during 30 years of healthcare practice.\n\nDr. Karl Maret  cell (831) 539-3255 and email soniclight@ebold.com\n","attachments":["https://downloads.regulations.gov/HHS-OASH-2026-0397-3602/attachment_2.pdf","https://downloads.regulations.gov/HHS-OASH-2026-0397-3602/attachment_1.pdf","https://downloads.regulations.gov/HHS-OASH-2026-0397-3602/attachment_1.docx","https://downloads.regulations.gov/HHS-OASH-2026-0397-3602/attachment_3.pdf"],"attachment_inventory":true,"withheld":false,"source":"https://www.regulations.gov/comment/HHS-OASH-2026-0397-3602","tags":["cancer-tumors","health-experiences","exposure-places","policy-standards","research-evidence"],"source_hash":"892c7f859773a88b7e5ee1adc3b179ca2dc99055d1c3f649584136b953b42a33","slug":"cancer-tumors-comment-3602","classification":{"id":"HHS-OASH-2026-0397-3602","body_sha256":"af1fe2b12576a7dcb094689c35dd780aa3415afb2e3e463b3cd32f32d3b8bfb9","status":"ai_reviewed","primary_topic":"standards","topics":[{"id":"standards","evidence":"charged with protecting the public, has exposure standards that are principally suitable for short-term exposure and o"},{"id":"infrastructure","evidence":"tion environment including sources from cell towers and antennas, WiFi and wireless transmitters, wireless devices in the ho"},{"id":"wifi","evidence":" sources from cell towers and antennas, WiFi and wireless transmitters, wireless devices in the home and office environment, cell "},{"id":"smart-meters","evidence":"l phones and other cordless phones, and wireless smart meters.
