HHS-OASH-2026-0397-6855 https://www.regulations.gov/comment/HHS-OASH-2026-0397-6855 The IARC cancer classification seems to have had little or no impact on protecting the public against risks associated with RF exposure. A major hampering factor has been the exposure guidelines by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) based only on the acute and very short-term thermal (heating) effects of RF radiation. These guidelines are used by the majority of countries worldwide. These guidelines were initially published approximately 20 years ago (18) and were updated in 2009(19); however, no changes were made to adapt to the rapidly increasing evidence of the harmful effects of RF and new RF signal characteristics and exposure from new technologies. ICNIRP, with the support of the WHO (10) and the major telecom companies, has made considerable efforts to convince countries worldwide to follow their guidelines. However, with the deployment of the 5th generation of microwave radiation, 5G, even the obsolete ICNIRP guidelines may be exceeded and may become an obstacle for the deployment of 5G (20). Thus, ICNIRP is preparing new guidelines that are briefly commented on below. However, as already published (9,10), the ICNIRP guidelines may be contradictory to a vast number of existing scientific reports demonstrating the harmful effects of RF radiation (21). Furthermore, there may perhaps also be conflicts of interests in terms of ties to the industry. Recommendation: Carry out research on the health impacts of 5G; revise the FCC’s current maximum RFR exposure levels to take into account the large volume of peer reviewed research indicating non-thermal related adverse health impacts of RFR.
