Nevertheless, it is always a good idea to practice precautionary measures. You can minimize your RF radiation exposure by using hands-free devices, such as earphones or speakerphones, to keep the phone away from your body. Additionally, limiting the duration of phone calls and using the phone in areas with a strong signal can reduce the intensity of exposure.
It is also worth noting that research in this field is ongoing, and new studies may provide further insights into the long-term effects of RF radiation. Staying informed about the latest research and guidelines from reputable sources can help you make informed decisions regarding smartphone usage and radiation exposure.
Types of Radiation Produced
The iPhone 11 generates two distinct types of radiation:
- RF-EMF: Like other mobile phones, Apple’s iPhone 11 employs radio frequencies to transmit and receive signals. These radio waves constitute a form of electromagnetic field (EMF) radiation. The International Association for Research on Cancer, affiliated with the World Health Organization, recognizes RF-EMF radiation as a potential carcinogen for humans. It has also been associated with fertility issues and certain types of cancer.
- ELF-EMF: In addition, the iPhone 11 emits extremely low frequency (ELF) EMF radiation simply by being powered on. ELF-EMF radiation is produced by electronic devices, and although the iPhone’s emissions in this regard may be low, it is worth acknowledging that this type of EMF radiation has been linked to cases of childhood leukemia.
It is important to be aware of these different forms of radiation and their potential implications for users of the iPhone 11.
The iPhone 11 and Its RF Radiation Emissions
Like any other mobile device, the iPhone 11 emits RF radiation as a natural aspect of its functioning. However, what implications does this hold for you as a user? To gain a comprehensive understanding, let’s delve into the concept of Specific Absorption Rate (SAR). SAR quantifies the rate at which the human body absorbs energy when exposed to a radio frequency electromagnetic field, serving as a crucial element in comprehending the potential effects of smartphone radiation on your well-being.
By considering the SAR value of a device, which indicates the amount of radiation absorbed by the body, you can make more informed decisions regarding your smartphone usage. Regulatory authorities set SAR limits to ensure that devices meet safety standards and minimize potential risks associated with RF radiation exposure. Understanding the SAR value of the iPhone 11 can help you evaluate and manage your exposure to RF radiation while using the device.

The Controversy Surrounding Apple’s Reported SAR Levels
Taking into account the valuable insights gained from the iPhone 7, it became evident that Apple faced accusations of potentially providing inaccurate information regarding SAR levels. Independent testing carried out by the Chicago Tribune involved the evaluation of the iPhone 7 and other smartphones. Alarming findings emerged, revealing that even at a distance of 5mm, the iPhone 7 exposed users to hazardous levels of RF-EMF radiation, contradicting Apple’s own test results. Consequently, this prompted an investigation by the FCC.
In 2020, an independent laboratory conducted further testing, this time focusing on the iPhone 11 Pro. Referring to the provided chart, we observe that the Pro models (specifically, models A2218, A2161, A2219, and A2220) exhibited SAR levels of 1.6 W/kg for the head and 1.17 W/kg for the body, well within the legal limits as reported.
However, recent testing conducted by the RF Exposure Lab unveiled concerning results. At a distance of 5mm, the iPhone 11 Pro yielded SAR levels of 3.8 W/kg, exceeding the legal limit by more than double. This disparity raises questions about the disparities between Apple’s test results and those obtained by other laboratories.
One potential explanation lies in the fact that Apple directly supplies test phones to the laboratories, while the Chicago Tribune and RF Exposure Lab purchased phones from retail sources. It is plausible that the phones provided by Apple for testing purposes differ in some aspects from the devices purchased by consumers.
Moreover, the issue of elevated SAR levels prompts an exploration into the factors contributing to the significant increase in the iPhone 11 Pro’s RF output.
One theory posits that the phone’s continuous data uploading may play a role in the heightened levels. A compelling video demonstrates the testing of the iPhone 11 alongside other phone models using an EMF meter, showcasing both standby mode and data uploading scenarios. The results present a persuasive case for further investigation.
- Disable Bluetooth functionality. One of the significant contributors to the radiation issue of the iPhone 11 is its constant search for a Bluetooth connection. To address this concern, you can easily resolve it by disabling Bluetooth in the phone’s settings. Alternatively, if Siri is enabled, you can simply say, “Siri, turn off Bluetooth.” It is important to note that turning off Bluetooth solely from the control center will disconnect connected devices but will not completely disable Bluetooth. To turn off Bluetooth in the settings, open the settings app, navigate to the Bluetooth section, and toggle it to the “off” position.
- Consider switching to 3G. While faster network speeds like 4G or 5G offer convenience, they also increase RF-EMF radiation exposure. While Airplane mode is the ideal option, you may need to use your cell phone occasionally. A good compromise is to connect your phone to 3G only.
