Check Your Phone's Radiation: SAR Value Checker

Look up your smartphone's SAR value for free. The SAR value (Specific Absorption Rate) measures the electromagnetic energy your body absorbs. EU limit: 2.0 W/kg. The lower, the better.

Every smartphone manual includes an RF Exposure notice, often hidden under Settings → General → About → Legal → RF Exposure.

What you should know

01Science
Is smartphone radiation harmful?
The WHO classifies mobile phone radiation as possibly carcinogenic (Class 2B, IARC). In weak signal conditions, your phone transmits at maximum power, meaning real-world exposure can far exceed the lab SAR value. Long-term studies show links between high RF exposure and health effects.
02Airplane mode
Does airplane mode stop phone radiation?
Yes. In airplane mode, all transmitting functions are disabled: no cellular, no WiFi, no Bluetooth. RF radiation drops to nearly zero. GPS remains in receive-only mode and does not emit radiation. The simplest protection measure for the night.
03Distance
How far should your phone be while sleeping?
At least 1–2 metres from your head. Exposure drops significantly even at 20–30 cm. Activate airplane mode or store your phone in a Faraday bag for complete signal blocking.
04Products
Do radiation protection stickers work?
No. Independent tests confirm EMF stickers have no shielding effect. Some can actually increase exposure by causing the phone to boost its transmit power. The only proven protection is certified Faraday shielding.
05Bedroom
Reduce electrosmog in the bedroom
Switch off your WiFi router at night, replace cordless DECT phones with wired alternatives, and avoid charging your phone beside the bed. Or use a TOCA Faraday bag for complete signal blocking.
Practical Tips
01Activate airplane mode while sleeping
02Use a Faraday bag for complete signal blocking
03Don't carry your phone directly against your body
04Use a headset instead of direct contact while calling
05Avoid calls when signal is weak (1–2 bars)
06Switch off your WiFi router at night
