5 Tips to Reduce EMF Exposure on Long Flights

December 11, 2024

Every day, EMFs surround us—from our phones and laptops to the Wi-Fi networks at home and in every coffee shop. But have you ever thought about EMFs on airplanes?

When we’re up at 30,000 feet, we’re closer to cosmic rays and surrounded by electronics that emit EMFs. Each year, around 2.7 million people take to the skies on over 44,000 flights daily, carrying their devices and connecting to in-flight Wi-Fi.

In this blog, you’ll get the real scoop on what EMFs mean for your health while flying. We’ll break down the facts, debunk myths, and share tips on staying safe if you’re concerned about EMF exposure.

What EMF/Radiation Exposure Do You Get at Airports or on Planes?

When you fly, there are various EMF sources around you—from airport scanners to in-flight WiFi.

But is it dangerous? Let’s break it down.

Airport Scanners

Before boarding, passengers pass through TSA’s millimeter-wave scanners, which emit low-level non-ionizing radiation, unlike the high-energy ionizing radiation of X-rays. The American Association of Physicists in Medicine found that the radiation exposure from these scanners is so low that it equals the amount you'd get by simply standing on the ground for 1.8 minutes.

Cosmic Radiation

Up at cruising altitude, cosmic radiation exposure increases due to the thinner atmosphere. For perspective, a coast-to-coast flight across the U.S. exposes you to about 0.035 mSv of cosmic radiation. While this may sound alarming, it’s actually considered safe for occasional flyers.

EMFs on the Plane

Inside the aircraft, EMFs from cockpit systems, in-flight entertainment, and passenger devices are everywhere. And due to the plane’s metal body (a partial Faraday cage), some EMF emissions stay trapped, amplifying the exposure.

WiFi Hotspots

Many airlines now offer WiFi, which connects either via ground towers or satellites. However, with more users and higher bandwidth, EMF radiation levels increase, further magnified by the Faraday Cage Effect.

How Much Radiation Do You Really Get from Air Travel?

Flying may not expose you to a ton of radiation, but it’s not entirely risk-free. Here’s the deal:

Flight Duration: The longer you’re in the air, the more radiation you’re soaking up. A quick 1-hour flight? No sweat. A long-haul across the ocean? That’s a bit more exposure.
Altitude: Higher flights = higher radiation. At 30,000 feet, there’s less atmosphere to shield you from cosmic rays, which means a bit more exposure the higher you go.
Latitude: Heading north or south? The closer you are to the poles; the more radiation you’ll face. Earth’s magnetic field deflects some cosmic rays toward the poles, leaving flights over these regions with slightly higher doses.

On average, cosmic radiation from flying only adds about 0.33 mSv (or 33 mrem) to your yearly exposure, roughly 11% of what we get from all natural radiation sources. So while it’s not zero, for most of us, it’s not enough to worry about.

Source of Natural Radiation	Average Annual Dose	Percent of Average Annual Dose
Internal (by Inhalation)	2.28 mSv (228 mrem)	73%
External (from Cosmic Exposure)	0.33 mSv (33 mrem)	11%
Internal (by Ingestion)	0.29 mSv (29 mrem)	9%
External (from Terrestrial Exposure)	0.21 mSv (21 mrem)	7%

Can EMFs on Airplanes Affect Your Health? What Studies Say

Many studies have looked at EMF exposure in closed environments. Some research suggests that EMF exposure can affect human health. A review published in the Journal of Exposure Science & Environmental Epidemiology found associations between EMF exposure and various health issues, including headaches and fatigue.

On airplanes, the confined space can increase exposure. A study by the National Institute for Occupational Safety and Health highlighted that passengers could face higher levels of EMFs during flights. While these effects are still debated, they should not be ignored.

Current Safety Standards

Aviation and health organizations have set safety standards for EMF exposure. The Federal Aviation Administration (FAA) and the World Health Organization (WHO) provide guidelines on EMF levels.
The FAA has established limits for EMF exposure in aviation environments. They aim to protect both passengers and crew members. The WHO recommends further research to better understand long-term effects.
Despite existing standards, many experts agree that the current guidelines may need updating. With the rise in technology and increasing EMF sources, revisiting these standards is crucial for passenger safety.

5 Ways To Limit Your Radiation Exposure In Long Haul Flights

While air travel EMF exposure is generally safe for most, taking steps to minimize it—especially on long-haul flights—can offer extra peace of mind. Here’s how you can protect yourself and your loved ones:

Use a Laptop Shield

Long flights are prime time to get some work done, watch a series, or dive into movies on your laptop. However, laptops emit EMFs across multiple frequencies.

To reduce this exposure, consider using a laptop shield, like the DefenderPad. This shield is designed to block up to 92% of radiation from your laptop, providing a safer workspace. FCC-tested, it combines non-grain oriented silicon steel with high conductivity aluminum for effective EMF protection, making it ideal for flights.

Invest in an Anti-Radiation Headset

Earbuds are a travel must-have, but traditional ones can transmit EMFs directly from your device. Anti-radiation headsets, like AirTube technology headsets, work with an air-filled tube that transmits sound without sending radiation to your ears.

According to Medical News Today, air-tube headsets can reduce radiation exposure by up to 98%, making them a safer choice for those extended playlists and in-flight movies.

Shield Your Phone with a Protective Wallet Case

Phones are more than entertainment—they’re also significant sources of EMFs. Protective wallet cases, use a combination of shielding materials that help deflect radiation away from your body.

This added layer of protection reduces radiation exposure without sacrificing access to your phone's functions, so you can safely enjoy all your in-flight apps and streaming services.

Wear a Protective Band if Pregnant

Long flights can be uncomfortable for everyone, but for pregnant travelers, there’s an added concern. EMF exposure is one consideration for expecting mothers on flights.

Belly armor, like the BabyGuard Anti-Radiation Maternity Band, uses silver shielding fibers and soft cotton to create a comfortable protective layer. Tested by third-party labs, these bands can block up to 99% of EMFs, ensuring safer travel conditions for both mom and baby.

Use Anti-Radiation Blankets for Infants and Kids

Children are more sensitive to EMF exposure, making protection particularly important on long flights. Anti-radiation blankets like Belly Armor’s Radiation Protection Blanket, woven with silver fibers, are designed to shield your little ones from EMFs while providing a soft, comforting cover.

This blanket reduces EMF exposure by up to 99%, offering peace of mind for parents during those hours in the air.

From protective bands to EMF-shielding blankets, these products help reduce exposure risks and make for safer travels. As the National Cancer Institute notes, taking small, proactive steps to limit EMF exposure is an effective way to protect your health on long flights.

Conclusion

Air travel exposes passengers to electromagnetic fields (EMFs), but understanding these sources and exposure factors can help you make informed choices. By using protective measures like laptop shields, anti-radiation headsets, and specialized clothing for pregnant travelers and children, you can significantly reduce EMF exposure during flights.

For most travelers, the radiation levels are low and unlikely to pose health risks. However, being proactive can enhance your peace of mind. Whether you’re a frequent flyer or on a long journey, these practical strategies can help create a healthier flying experience. Safe travels!
