In today’s world, smartphones have become indispensable, used for work, entertainment, and communication. However, an increasing concern has surfaced regarding the smartphone radiation that these devices emit. How much radiation are we exposed to through these essential gadgets? Let’s delve into the specifics of radiation emissions by smartphone, measured in Specific Absorption Rate (SAR), to better understand their potential effects.
What is SAR and Why It Matters
The radiation emitted by smartphones is measured using a standard called Specific Absorption Rate (SAR), which calculates the electromagnetic energy absorbed by human tissue when using a mobile device. The European Union (EU) sets the SAR limit at 2 watts per kilogram (W/kg), measured over 10 grams of tissue. This ensures that devices stay within safe radiation levels.
The SAR value of a phone can be measured in two ways:
- At the ear – when the phone is held up for calls.
- At the body – when the phone is carried in pockets or held close.
Understanding these values is critical for making informed decisions about how much radiation is emitted by smartphones we use daily.
Radiation is Emitted by Popular Smartphones
Smartphone with the Highest Radiation Emission
Based on data from the German Federal Office for Radiation Protection, here are the smartphones that emit the highest levels of radiation:
- Motorola Edge – SAR value: 1.79 W/kg
- ZTE Axon 11 5G – SAR value: 1.59 W/kg
- OnePlus 6T – SAR value: 1.55 W/kg
- Sony Xperia AX2 Plus – SAR value: 1.41 W/kg
- Google Pixel 3 XL/3A XL – SAR value: 1.39 W/kg
The Motorola Edge leads the list with a radiation emission close to the EU limit, making it one of the most critical devices to consider for users concerned about prolonged exposure.
Smartphones with the Lowest Radiation Emission
For those seeking phones with minimal radiation exposure, several models stand out with low SAR values:
- ZTE Blade V10 – SAR value: 0.13 W/kg
- Samsung Galaxy Note 10+ – SAR value: 0.19 W/kg
- Samsung Galaxy S10 5G – SAR value: 0.26 W/kg
- Samsung Galaxy A80 – SAR value: 0.24 W/kg
- Samsung Galaxy A10 – SAR value: 0.24 W/kg
Samsung’s models are particularly noteworthy for maintaining low radiation emissions, making them favorable for users concerned about safety.
Are There Health Risks from Smartphone Radiation?
Despite the alarm over radiation emitted by smartphones, there is currently no definitive research proving its harmful effects on human health. However, people who use their phones for extended periods may wish to monitor their exposure by choosing models with lower SAR values.
The key takeaway is that while radiation levels vary across devices, smartphones with SAR values below the regulated limit are considered safe to use. By selecting phones with low radiation emissions, users can further reduce potential exposure and ensure compliance with safety standards.
Conclusion
Understanding how much radiation is emitted by popular smartphones helps users make informed decisions about the devices they rely on daily. Whether you are choosing a phone with a high or low SAR value, awareness, and caution in use—such as limiting exposure during long calls—can minimize any potential risks.
Choose wisely, and stay informed about the smartphone radiation you might be exposed to.
