Wireless radiation and electromagnetic fields (EMF) are a rapidly increasing environmental exposure.
Cell phones, cell towers, and wireless devices emit radiofrequency radiation, a type of EMF. Government limits are decades old. Scientists are calling for safeguards to protect human health and wildlife.
Our Work
We are leading the way towards a safe technology future.
The Wireless and EMF Program at Environmental Health Sciences aims to:
- Advance scientific understanding of the health
and environmental impacts from exposure. - Support science-based, protective regulations
and transparent oversight. - Promote innovative solutions that mitigate health and environmental risk.
Watch Now
Linda Birnbaum PhD, former director of the National Institutes of Environmental Health and the National Toxicology Program, dives into the science behind EMF’s health impacts, the “clear evidence” of cancer findings in the NIH animal study, the increased vulnerability of children and pregnant women, and the actions needed to reduce cell phone exposure.
FAQ
- What is EMF?
Electromagnetic fields (EMFs) are ubiquitous in the modern world. They are invisible, energized waves composed of electric and magnetic fields. Growing research suggests artificially generated non-ionizing EMFs can have harmful effects on human health and the environment.
- How are we exposed to EMFs?
Scientists have focused on the health effects of two types of non-ionizing EMF:
- Wireless radiofrequency radiation, which is emitted by all wireless devices such as cell phones, tablets, laptops, smart devices, Bluetooth, cell towers, and 5G.
- Magnetic field extremely low frequency EMF (often referred to as just “EMF”), which is emitted by electronics, charging cords, and power lines.

- What are the health effects of exposure to EMF?
Studies have reported associations between exposure to EMF and cancer, genetic effects, decreased testosterone, sperm damage, memory problems, altered thyroid hormone levels, and altered neurotransmitters in the brain. Studies have also found impacts to wildlife, plants and trees.
Non-ionizing EMFs have been found to increase oxidative stress in the body. This can lead to inflammation, disrupting healthy functions and increasing the risk of chronic disease.
- How is EMF exposure regulated?
In the U.S., the Federal Communications Commission’s regulatory limits for wireless radiation exposure were set in 1996. Since that time, there has been no review of these limits to ensure they are based on up-to-date science. FCC limits only prevent short-term tissue overheating, ignoring biological effects and long-term exposure risks.
The U.S. does not have any limits for magnetic field EMF exposure, a serious regulatory gap.
- What do experts say?
Numerous scientific and medical organizations, including the American Academy of Pediatrics and California Department of Health, are calling for a scientific review of current regulations as well as public health advice to reduce exposure.
The New Hampshire State Commission issued a Report on 5G and wireless technology recommending cell towers be distanced from homes and schools. Click here to learn more about experts’ safety recommendations.
- What are some ways to reduce exposure?There are many simple ways to protect yourself.
-
Distance cell phones and wireless devices away from your head and body.
-
Do not carry cell phones in your pocket or bra.
-
Use speakerphone or wired airtube headphones for calls, and corded and ethernet tech rather than wireless or Bluetooth.
-
Turn your Wi-Fi off when it’s not in use.
The Santa Clara Medical Association issued Best Practices for Safe Technology in Schools , and the Maryland State Environmental Health and Protection Advisory Council provides Guidelines to Reduce Wireless and EMF.

- U.S. regulations fail to protect wildlife from cell tower and wireless radiation, science review finds
A science and policy review published in Frontiers in Public Health documents how increasing levels of non-ionizing electromagnetic (EMF) radiation in the environment, including the wireless radiation from cell towers, combined with the absence of regulations protecting wildlife from harmful impacts, are “leading to an ecological crisis.”
- A rare look behind the RF curtain as WHO review of animal studies takes center stage
The World Health Organization (WHO) has been trying to manipulate its long-running assessment of radiofrequency (RF)–cancer risks, according to a prominent Swiss toxicologist. Meike Mevissen, who was commissioned by the WHO to lead a systematic review on RF and cancer in animals six years ago, is charging that her study team had to defend itself from interference.
- Arizona county officials approve cell tower permit, settlement
The Navajo County Board of Supervisors voted Jan. 27 after a lengthy call to the public that included appeals from residents and supporters of a community east of Snowflake who say they are disabled by sensitivity to chemicals and electromagnetic fields.
- HHS launches cellphone radiation health study to determine safety levels
A cell phone radiation health study has been launched by the Department of Health and Human Services to investigate whether electromagnetic radiation from phones and cell towers could harm Americans.
- U.S. cell tower & cell phone radiation policy fails public health, new paper finds
A new review paper published in Frontiers in Public Health details the outdated policies and gaps in oversight and enforcement that characterize the U.S.’ regulatory framework for cell towers, cell phones, Wi-Fi and wireless radiation. The author, Theodora Scarato, is the director of Environmental Health Sciences’ Wireless & EMF program.
