Is living near a mobile phone tower harmful?

Health effects are unlikely when radio-wave exposure stays below international guidelines. Access near tower antennas giving off radio waves is restricted where limits may be exceeded. Some long-term questions remain unsettled.

Why people believe it
WHO says reports of studies whose findings have not been confirmed can leave people feeling uncertain. It also describes worries about how towers look. WHO also describes people feeling excluded from decisions about tower locations. A Dutch report’s background also describes people linking headaches or disturbed sleep to towers. WHO says their suffering deserves recognition. Yet these signals have not been shown to cause the symptoms.
“The radiation is dangerous”
Antenna power, direction and your position all affect exposure. The most powerful antennas tend to sit high up. They are designed to send most power towards the horizon, leaving small exposures underneath.
A 2025 UK study surveyed 30 public locations near 56 active 5G base stations. The study measured radio-wave exposure at frequencies (how often waves repeat each second) from 420 MHz to 6 GHz. Across these frequencies, total radio-wave exposure averaged 0.2% of the international public reference levels from 1998. These locations were chosen for access and a clear view of antennas. They were not a random sample of homes.
“It causes cancer”
A British study compared 1,397 children with cancer, aged 0–4, with 5,588 children used for comparison. It found no link between childhood cancer and mothers’ estimated tower exposure during pregnancy. It did not investigate health effects from tower exposure after birth. Errors in estimating exposure could have hidden a real increase in risk.
A 2024 review looked at fixed transmitters, including towers and broadcasting antennas. It found moderate-certainty evidence that these likely do not increase childhood leukaemia risk. For childhood brain tumours, it found low-certainty evidence that fixed-transmitter exposure may not increase risk. This was based on few studies. No studies met the review’s rules for fixed-transmitter exposure and the adult tumours it sought.
There are concerning animal findings. The original 2025 animal-cancer review assessed evidence of increases in two tumour types in male rats. It rated this evidence as high certainty. Certainty means confidence in how closely an estimated effect matches the actual effect. The review was later corrected; this page reports its original version. Its authors say working out human risk from animal results is especially complicated. The authors of a 2025 advocacy commentary also argue that WHO-commissioned reviews have flaws. They argue these flaws prevent the reviews from proving the safety of cell phones and other wireless communication devices.
“It causes headaches or poor sleep”
A 2010 review found strong evidence against a link between tower-signal exposure and immediate symptoms at the levels tested. The trials tested levels up to 10 volts per metre. Participants did not know the exposure. It separately found too little evidence for firm conclusions about long-term, low-level exposure.
A broader 2024 review found that available research suggests below-guideline exposure does not cause the symptoms it prioritised. However, it rated the evidence very uncertain. It covered both brain and whole-body exposure, rather than towers alone.
Thinking tool: measure exposure, not just distance
Distance from a tower is only weakly linked to actual exposure. Antenna direction and power help explain why. Some studies surveyed non-specific symptoms at one point in time. In these studies, links appeared more often with rough distance estimates than with better exposure measurements. Random errors in estimating exposure may also weaken a real exposure–response link, if one exists. For other claims, ask what researchers measured. Was it the thing suspected of causing harm or just something easier to count?
Official positions, with dates
WHO, May 2006: no convincing evidence that weak tower signals cause harm. IARC, 31 May 2011: radiofrequency fields were classified as “possibly carcinogenic to humans”, based on wireless-phone evidence. Environmental evidence was inadequate. That assessment did not put a number on the risk.
ICNIRP, March 2020: revised guidelines aim to avoid excessive local and whole-body heating. UK Health Security Agency, updated July 2024: expert reviews support health effects being unlikely below international guidelines.
What people also ask
What are the effects of mobile tower radiation on health?
Effects are unlikely below guideline levels. Longer-term symptom evidence remains very uncertain.
How far away should your house be from a cell phone tower?
Distance from a tower is only weakly linked to exposure. Exposure also depends on antenna direction and power. Measured or calculated exposure can be expressed as a fraction of the guideline level.
Is it safe to stay near a mobile tower?
UK guidance supports reassurance below exposure limits. WHO describes restricted access near antennas where limits may be exceeded.
Does living by a cell tower affect your health?
The study of cancers at ages 0–4 found no association with estimated maternal tower exposure during pregnancy. It did not investigate health effects from tower exposure after birth.

“Considering the very low exposure levels and research results collected to date, there is no convincing scientific evidence that the weak RF signals from base stations and wireless networks cause adverse health effects.”
