When it comes to the radiation emitted by phones, the specific absorption rate (SAR) is used as a measure. SAR represents the rate at which the body absorbs radiofrequency energy from the phone. The SAR value is measured in watts per kilogram (W/kg).
Different phone models can have varying SAR values, and these values are typically provided by manufacturers. It's important to note that regulatory bodies in different countries have set limits on the maximum SAR value allowed for mobile devices to ensure they comply with safety standards.
To determine which phone has more radiation, you would need to compare the SAR values of the specific phone models you're interested in. These values are usually available in the phone's technical specifications or can be obtained from the manufacturer's website. Remember that lower SAR values indicate lower radiation emissions, while higher SAR values indicate higher emissions.
It's worth mentioning that modern smartphones are designed to comply with safety regulations and emit radiation within the permissible limits. If you're concerned about potential exposure, you can also minimize your exposure to radiation by using hands-free devices, such as headphones or speakerphone, and keeping your phone at a distance from your body when not in use.
