Popular smartphones typically emit non-ionizing radiation in the form of radiofrequency (RF) waves. These waves are a type of electromagnetic radiation that falls within the non-ionizing part of the electromagnetic spectrum. The specific amount of RF radiation emitted by smartphones can vary depending on several factors, including the device model, network technology, signal strength, and usage.
To ensure the safety of consumers, regulatory bodies around the world have established guidelines and limits for the specific absorption rate (SAR) of smartphones. SAR is a measure of the rate at which RF energy is absorbed by the body when using a mobile phone. The SAR value represents the maximum allowed radiation exposure for a specific device.
SAR values are typically measured in units of watts per kilogram (W/kg). The specific SAR values for smartphones can usually be found in the device's user manual or on the manufacturer's website. Different countries have different SAR limits, but most regulatory agencies have set the limit at 1.6 W/kg averaged over 1 gram of tissue.
It's important to note that numerous studies have been conducted to assess the potential health effects of RF radiation from smartphones, and the general consensus among scientific organizations is that the current levels of RF exposure from smartphones are unlikely to cause adverse health effects. However, ongoing research in this field continues to evaluate the long-term effects of RF radiation exposure.
If you are concerned about the RF radiation emitted by your smartphone, you can check the SAR value provided by the manufacturer and compare it to the regulatory limits set in your country. Additionally, using hands-free options like speakerphone or a wired headset can reduce the proximity of the device to your body during phone calls, further minimizing potential exposure.
