SAMSUNG GALAXY A51 5G Safety Tip:

How Much Will Turning Off Wi-Fi and Bluetooth Reduce Radiation?

This SAR chart reveals how turning off Wi-Fi and Bluetooth on your SAMSUNG GALAXY A51 5G can significantly reduce your exposure to radiation. Our SAR comparison chart shows that by simply turning off Wi-Fi and Bluetooth transmitters, you can lower the RF radiation exposure to your head by 32.1%, and you can lower exposure to the body by 29.4%, when considering these differences between cellular-only (Wi-Fi/Bluetooth OFF) and simultaneous use exposure (Wi-Fi/Bluetooth ON), a wise way to reduce excessive phone radiation is to tap off unnecessary transmitters when not in use! Additionally, when using your phone as a hotspot, turning off Bluetooth can reduce your exposure by up to 12.2% according to the FCC SAR report for device number A3LSMA515U.

Comparison of SAR levels between cellular-only and simultaneous exposure
Cellular Only	(% DIFF)	Wi-Fi + Cellular
0.821 W/kg	HEAD 32.1%	1.210 W/kg
1.037 W/kg	BODY 29.4%	1.468 W/kg
1.207 W/kg	HOTSPOT 12.2%	1.354 W/kg

Key Takeaways

Children vs Adults: Children have higher SAR levels due to thinner skulls and developing tissues, making them more vulnerable to radiation.
Wi-Fi Impact: Simultaneous use of cellular and Wi-Fi transmission increases SAR levels for all age groups.
Precautionary Measures: Using radiation protection products like QuantaCase can help mitigate these risks, especially for younger users.

By understanding these differences, parents and guardians can make informed decisions to better protect their children from excessive microwave radiation exposure, emphasizing the need for safer smartphone usage practices and protective accessories like QuantaCase.

Children vs Adults Radiation Exposure

The Specific Absorption Rate (SAR) of a mobile device measures the amount of radio frequency energy absorbed by the body during device usage.

The SAR values for the galaxy-a51-5g (FCC ID A3LSMA515U) are as follows:

0.82 W/kg when held at the head with cellular transmission only
1.04 W/kg when worn on the body with cellular transmission only
1.21 W/kg when used as a Hotspot or Airplay
1.21 W/kg when held at the head with simultaneous cellular and Wi-Fi transmission
1.47 W/kg when worn on the body with simultaneous cellular and Wi-Fi transmission
1.35 when used as a Hotspot simultaneously with other transmitters active.
