DIGITAL LIFE
Cell phones emit radiation, specifically electromagnetic radiation. This radiation is generated when the phone connects to cell towers or Wi-Fi networks to transmit data and make calls. And knowing this, many people are concerned about constant contact with their cell phones.
Although radiofrequency (RF) radiation is low energy, prolonged contact with the head or body (such as when making long calls or sleeping near the cell phone) increases exposure, which leads to concerns about possible cumulative effects.
The impact of this exposure is still the subject of scientific studies. The radiation emitted by cell phones is classified as radiofrequency radiation, which is non-ionizing. This means that it does not have enough energy to cause direct damage to DNA.
Therefore, knowing which cell phone models emit the most radiation is information to consider. There is growing interest in this topic and the demand for this information has encouraged manufacturers and regulators to more clearly state SAR levels in device specifications, enabling consumers to make a more informed choice when purchasing cell phones.
The amount of radiation emitted is measured by the Specific Absorption Rate (SAR), which indicates how much of the radiation energy is absorbed by the human body.
Which cell phones emit the most radiation in 2024?...In 2024, lists of smartphones with the highest radiation emissions are still being made, using the SAR (Specific Absorption Rate) metric to assess how much radiofrequency energy the body absorbs during use of the device. Here are the models with the highest levels, according to the BfS (German Federal Office for Radiation Protection), which provides a list of smartphones with the highest radiation levels, measured by Absorption Rate:
2-Xiaomi Mi A1: 1.75 W/kg
3-OnePlus 5T: 1.64 W/kg
4-ZTE Axon 11 5G: 1.59 W/kg
5-OnePlus 6T: 1.55 W/kg
6-Google Pixel 4a – SAR of 1.37 W/kg
7-Sony Xperia XZ1 Compact – SAR of 1.36 W/kg
In contrast, smartphones with the lowest radiation levels include:
1-Samsung Galaxy A80: 0.22 W/kg
2-Samsung Galaxy Note10+ 5G: 0.19 W/kg
3-ZTE Blade V10: 0.17 W/kg
To access the SAR values of different devices, you can directly access the link site.
How the measurement is performed:
-Test environment: devices are tested in controlled environments that simulate real-world usage conditions, such as the position of the cell phone in relation to the user's head.
-Human body simulators: a model of the human body made of a material that mimics the electrical properties of human tissue is used. This model is filled with a liquid that simulates radiation absorption.
-Measurement equipment: antennas and sensors are placed around the simulator to measure the intensity of the radiation emitted by the cell phone. These measurements are taken while the cell phone is in use, typically during calls.
SAR calculation: the SAR value is calculated in watts per kilogram (W/kg), reflecting the amount of energy absorbed by a mass of 1 kg of tissue in a given time.
These tests are performed by accredited laboratories and must follow guidelines established by regulatory bodies, such as the International Commission on Radiological Protection (ICRP) and the World Health Organization (WHO). To find out if your mobile phone emits too much radiation, you can follow a few steps:
-Check the Specific Absorption Rate (SAR)
-Each mobile phone has a SAR rating, which indicates the amount of radiation absorbed by the body during use. This information is usually available in the device's technical specifications or in the user manual. The SAR value is measured in watts per kilogram (W/kg).
-A SAR below 1.6 W/kg is considered safe by the US Federal Communications Commission (FCC).
Consult lists and rankings:
There are lists that classify smartphones according to radiation levels. The German Federal Office for Radiation Protection (BfS), for example, provides an up-to-date list of mobile phones with the highest and lowest radiation levels. You can access this information directly on the BfS website or on other websites that compile data on mobile device radiation.
Use monitoring apps...There are apps available that can provide real-time information about the radiation emitted by your phone, although accuracy may vary.
Analyze your device usage...If you frequently use your phone for calls, especially in areas with weak signal strength, the radiation may be higher. Consider using headphones or a speakerphone to reduce your exposure.
