• New research suggests current cell phone radiation limits are 15 to 900 times higher than cancer-protective levels
• FDA removed webpages declaring cell phones safe after Health Secretary RFK Jr. raised health concerns
• WHO-funded reviews now show ‘high certainty’ evidence linking RF radiation to brain and heart tumors in animals

Current cell phone radiation safety limits may be dangerously inadequate, according to a March 2026 risk assessment that found exposure limits are up to 900 times higher than levels needed to protect against cancer.

The analysis by Dr. Ronald L. Melnick, a retired toxicologist from the National Institute of Environmental Health Sciences, and Dr. Joel M. Moskowitz from UC Berkeley’s School of Public Health calculated that health-protective radiation exposure should be 0.8 to 5 milliwatts per kilogram for cancer protection. Current public limits allow 80 milliwatts per kilogram.

The findings come as the U.S. government shifts its stance on cell phone safety. In January 2026, the FDA removed multiple webpages that previously declared cell phones safe for consumer use. Health Secretary Robert F. Kennedy Jr. announced a new federal study investigating potential health effects, calling electromagnetic radiation “a major health concern.”

“Our analysis clearly demonstrates that the current limits for cell phones and wireless networks are structurally incapable of protecting human health,” Melnick said in a press release.

The research found current limits are also 8 to 24 times higher than levels needed to protect male reproductive health. Scientists analyzed exposure data against limits set by the Federal Communications Commission and international radiation protection agencies.

Supporting evidence emerged in 2025 when WHO-commissioned systematic reviews concluded there is “high certainty” scientific evidence linking wireless radiation to gliomas in the brain and malignant schwannomas in the heart. The WHO had previously classified cell phone radiation as “possibly carcinogenic” in 2011.

Cancer rates among young adults aged 15 to 39 show concerning trends. A March 2025 French health study found glioblastoma incidence increased 6.11% annually between 2000 and 2020, representing a 233% overall increase over two decades.

The FCC has not updated radiation limits since 1996 and continues to defy a 2021 court order requiring better explanation of how current limits protect public health. The court directed review of 11,000 pages of evidence claiming wireless radiation harms people and the environment.

Industry groups maintain their position that no credible evidence links wireless devices to health problems. A CTIA spokesperson told Fox News Digital that radiofrequency energy “has not been shown to cause health problems, according to the consensus of the international scientific community.”

Twenty-two states have implemented cellphone restrictions in schools under the Make America Healthy Again movement, citing radiation exposure concerns during critical developmental years alongside mental health considerations.
