Strålskyddsstiftelsen reports on a new pilot study by Lennart Hardell and Mona Nilsson, published in July 2026 in Fortune Journal of Health Sciences. Measurements on two SAS flights found peak radiofrequency levels of 299,000–651,000 μW/m² in a cabin with a new satellite-based high-speed Wi-Fi system, versus 8,310–69,100 μW/m² with an older system — up to 10–80× higher. The levels remain far below ICNIRP guideline values but are tens of thousands of times above the EUROPAEM 2016 precautionary Wi-Fi recommendations. The authors call for larger independent studies and a health risk assessment before wide-scale deployment, highlighting cabin crew, frequent flyers, pregnant women, children, and electrosensitive individuals.

Quotes (our translation)

"A new Swedish pilot study shows that passengers on flights with high-speed WiFi may be exposed to significantly higher levels of radiofrequency microwave radiation than on flights with earlier WiFi systems."

[original: "En ny svensk pilotstudie visar att passagerare ombord på flygplan med high-speed WiFi (höghastighets-WiFi) kan utsättas för betydligt högre nivåer av radiofrekvent mikrovågsstrålning än på flygplan med tidigare WiFi-system."]

"On the aircraft with high-speed Wi-Fi, maximum radiation levels between 299,000 and 651,000 microwatts per square metre (µW/m²) were measured."

[original: "På flygplanet med höghastighets-Wi-Fi uppmättes maximala strålningsnivåer mellan 299 000 och 651 000 mikrowatt per kvadratmeter (µW/m²)."]

"This means that the highest measured levels were around 10–80 times higher with the new system."

[original: "Det innebär att de högsta uppmätta nivåerna var omkring 10–80 gånger högre med det nya systemet."]

— Strålskyddsstiftelsen

"The researchers therefore call for larger and independent studies of radiofrequency microwave radiation on board aircraft, along with a health risk assessment before the technology is deployed at scale."

[original: "Forskarna efterlyser därför större och oberoende studier av radiofrekvent mikrovågsstrålning ombord på flygplan samt en hälsoriskbedömning innan tekniken införs i stor skala."]
