Wi‑Fi and mobile radiation does not alter teen DNA

RF energy is a type of non-ionizing radiation. Non-ionizing radiation is not strong enough to directly affect the structure of atoms or damage DNA; however, it does cause atoms to vibrate, which can cause them to heat up.

There are many factors that influence whether damaged DNA will lead to tumors. NTP plans to conduct additional studies to learn more about how RFR might cause DNA damage. Please see the FAQs below for more information about the specific studies and NTP’s cell phone RFR program. NIEHS scientists in the Division of Translational Toxicology, which supports the NTP, undertook research to better understand some of the findings seen in the earlier RFR rodent studies reported in NTP Technical reports TR-595 and TR-596.

In 2019, the NTP scientists published ... DNA damage in the frontal cortex and hippocampus of male rat brains and the blood cells of female mice. In 2018, the Ramazzini Cancer Research Institute study of cell phone radiation and cancer published its results and conclusion that 'The RI findings on far field exposure to RFR are consistent with and reinforce ...

Sperm DNA is damaged by phthalates, ... et al. (2026). Exposure to hexavalent chromium and 1800 MHz electromagnetic radiation can synergistically induce intracellular DNA damage in mouse embryonic fibroblasts....

Animal studies show that exposure to RF radiation during critical developmental windows can alter neurodevelopment, cognitive function, motor activity, and emotional behavior. Studies have also reported impacts to oxidative stress regulation, apoptosis, DNA repair, synaptic plasticity, and neuroinflammation, leading to behavioral changes and anxiety-like responses.

Documented impacts include reduced sperm count, motility, and concentration; DNA damage; altered structure; and higher rates of erectile dysfunction. A literature review on the effects to male reproductive hormones concluded testosterone reduction.

Based on peer-reviewed studies over at least five decades on wireless radiation (or radio-frequency radiation – RFR), the extremely complex matrix of health effects on mood come from these means and mechanisms of action: oxidative stress and the subsequent formation of free-radicals and brain inflammation · an array of cellular stress responses (following oxidative stress), including (but not limited to) the induction of heat shock proteins, DNA damage, and apoptosis (cell death).

Wi-Fi routers communicate using ... of the electromagnetic spectrum. Unlike X-rays or gamma rays, it cannot knock electrons off atoms or directly damage your DNA....

This places Wi-Fi in the same broad category as radio signals, microwaves, and cell phone transmissions, all of which sit on the low-energy end of the electromagnetic spectrum. Unlike X-rays or ultraviolet light, non-ionizing radiation does not carry enough energy to break chemical bonds or damage DNA directly.
