Radiation and Flying
Firstly, airline travel subjects you to significant levels of cosmic rays or ‘cosmic radiation’. When I say cosmic radiation I’m referring to a collection of different types of radiation from many different of sources – the most important being cosmic background microwave radiation.
This is quite different to the electromagnetic fields (EMFs) I usually I talk about.
Cosmic radiation is a naturally occurring form of ionizing radiation produced by the sun and other stars and planets. The earth’s atmosphere and magnetic field protects the earth from most of this cosmic radiation. But when you fly, because of the altitude, this protection is greatly diminished.
For instance, flying from New York to Los Angeles exposes you to approximately 6 times as much radiation as a typical dental x-ray. A 10-hour flight across the North Atlantic exposes to more than double that amount.
EMFs in Planes
fly low emfNot surprisingly airplanes emit significant levels of electromagnetic fields (EMFs) and always have done.
Basically there are two types of EMFs present : low-frequency EMFs and radio frequency or WiFi radiation – I’ll speak about WiFi radiation in planes more fully below.
On the low frequency side, electric and magnetic fields are created in a similar way to in a home setting, except it’s way more complicated. In airplanes electrical engineers are given free reign. Transformers, rectifiers and inverters are used liberally to change the voltage or type of current.
Sources Of EMFs In Planes
Here are some sources of EMFs in planes :
. communications equipment
. jet engines
. cockpit computers
. electrical wiring
. electrical sensors
. static electricity in the fuselage
Why Are EMFs In Planes Dangerous?
Firstly, a planes metallic structure can intensify the effects of EMF exposures, particularly radio frequency radiation (aka wireless). It’s called the Faraday cage effect. This radiation is trapped in a metal enclosure which exacerbates the effects of this radiation. Would you consider sticking your head inside a microwave oven when it’s turned on? I don’t think so.
Secondly, it’s not just a about airplanes. It’s about EMFs per se. There is a significant amount of research that points to numerous adverse biological effects of these man-made EMF exposures, including:
. single and double strand DNA breaks
. breaks down the blood-brain barrier
. major organ damage
. compromises cell membranes
. immune system suppression
These exposures are linked to a number of serious diseases including multiple sclerosis, Parkinson’s disease, Alzheimer’s, cardiovascular disease, brain tumors and cancer.
WiFi Radiation In Planes
In addition to the cosmic radiation and EMFs generated from the planes’ electrical and communication system, over the last few years WiFi radiation has also been introduced into the toxic soup of airline travel.
When we talk about WiFi radiation we are actually talking about devices that use radio-frequency or microwave radiation to send data back and forth through the air, wirelessly. The problem is that this WiFi radiation can penetrate pretty much everything that stands in it’s path, including you.

How To Choose A WiFi Free Flight
According to a survey conducted by Routehappy, a company that evaluates in-flight amenities, 39% of airlines worldwide now have WiFi fully rolled out. Using the data from their survey I’ve compiled a WiFi radiation in planes analysis in the form of a bar chart, see below:
To compile my bar chart I took the data from Routehappy.com which shows for the worlds top airlines the percentage of ASMs (number of seats multiplied by number of miles flown) with at least a chance of WiFi, and inverted it.
When I first did this analysis, in 2016, the data was showing that only one airline, Scoot, was offering 100% WiFi coverage. Now there are three airlines offering 100% WiFi coverage; Scoot, Virgin America and Icelandair.
So in my bar chart, because in principal there is zero chance of booking a WiFi free flight with Scoot, Virgin America and Icelandair they are shown as 0% – meaning, if you are concerned about in-flight WiFi radiation exposures you should avoid booking with these airlines.
Airlines To Choose If You’re Concerned About WiFi Radiation – Currently
My bar chart shows that your best chance of flying WiFi free is to book with Philippine Airlines followed closely by Iberia and Air Europa.
Three points to note:
. You’ve less chance of flying WiFi free on U.S. airlines – 80% of their seat miles offer a full chance of WiFi as opposed to non-U.S. airlines, for which only 28% of seat miles offer at least a chance of WiFi
. 61% of available seat miles worldwide still have no Wi-Fi compared to 69% last year
. This data is changing fast as Airlines are eager to offer WiFi to seduce their clients
From Regular WiFi To Super WiFi
This analysis masks the level of radio frequency radiation emissions you are being subjected to. Most airlines, if they do offer WiFi, currently offer fairly low download speeds which implies lower radiation exposures. But Fortune.com reports that “passengers now demand a home broadband-like experience….so far only a few airlines meet that standard”.
The worst offender is JetBlue which is reported to be nearing completion of a fleet-wide broadband roll-out that would allow passengers to access streaming services – which implies higher wireless radiation emissions.
This WiFi roll-out is clearly demand driven. A 2016 survey of airline passengers by Honeywell Aerospace reveals that travelers now “expect a reliable connection to stay in touch with their friends and family, get work done, or be entertained.”
But airlines are not totally blamed. The Honeywell Survey found that over 20% of passengers have already abandoned their preferred airline for another company with better in-flight WiFi.
Tips For Flying Low EMF
Here are my tips for flying low EMF. Try to avoid:
. booking with airlines that have 100% of their fleet equipped with WiFi
. sitting in close proximity to the jet engines
. sitting near the WiFi routers – ask the stewards where these are, they might not know but you can ask
. the window seats, which expose you to higher levels of cosmic radiation
. flying during the daytime to minimize your exposure to cosmic radiation – prefer nighttime flights
This might seem like a lot of things to avoid and you’re probably thinking, where do I sit? Well, you’ve really got to do your best within these parameters. And then relax…
