The electromagnetic fields (EMF) emitted by an iPhone are generally low, but they do exist due to its wireless capabilities like Wi-Fi, Bluetooth, and cellular communication. The main source of EMF is the radiofrequency (RF) radiation produced when the phone is in use for calls, internet browsing, or data transfer.
To give you an idea of the levels:
1. **Specific Absorption Rate (SAR)**: The SAR is the measure of the rate at which the body absorbs RF energy when exposed to EMF. For iPhones, the SAR value typically ranges between **0.99 to 1.19 watts per kilogram** (W/kg), which is well below the regulatory limits. In most countries, the legal limit for SAR is around **1.6 W/kg**.
2. **Type of EMF**: The EMF emitted by iPhones is non-ionizing radiation, meaning it doesnβt have enough energy to remove electrons from atoms or molecules, so itβs considered to have a lower risk compared to ionizing radiation (like X-rays).
3. **Exposure**: The EMF exposure depends on factors such as the distance from the phone (holding it close to your ear versus using speakerphone) and its activity (e.g., talking vs. just being idle).
So, while the EMF emitted by an iPhone is low and generally considered safe by regulatory standards, prolonged exposure can still be a concern for some people, especially when holding the phone close to the body for long periods. If you want to minimize exposure, you can use speakerphone, wireless earphones, or keep the phone further from your body when not in use.
