So my friend is an iPhone owner, she's a retired teacher, and the iPhone is her only computer and communication device. She's asked me a couple of times, because she does worry, whether smartphones are sending harmful radiation into her body. And I've always assured her, explained how there are different types of radiation, EMF is non-ionizing, and the wattage/power levels are so small, that it's not a concern. I may have egg on my face when she starts reading these headlines.

Tell her to read past the headlines. This is about the heat dissipation (and Apple is apparently fixing this with a sw update). While you’re technically wrong if the question really was “is the radiation safe” since heat is technically radiation, that’s not what lay people are asking about when they are asking about radiation concerns (ie EM radiation). To reiterate. This is about how much heat the iPhone generates was found to exceed limits. Apple contends that this is because of French testing protocols and not a real issue. Unclear who’s in the wrong, but certainly nothing to do with EM radiation. > The company noted that it believed the issue was “related to a specific testing protocol used by French regulators and not a safety concern.” French officials stated that they were eager to test the software update and lift their ban on sales of the iPhone 12. > The EU's standards note that within a phone's typical frequency range, the main danger of excess radiation is not changes to cells or chemicals in the body, leading to cancer, but "whole-body heat stress and excessive localized heating of tissues." The vast majority of mobile phone research indicates no adverse effects from regular exposure to the non-ionizing frequencies phones use to communicate.

  Are you trying to say that this is all about the battery and CPU heating up inside the phone? So why does the chart in TFA indicate EM frequencies? https://www.who.int/news-room/questions-and-answers/item/radiation-electromagnetic-fields#:~:text=The%20main%20effect%20of%20radiofrequency,can%20be%20harmful%20to%20health https://www.who.int/news-room/questions-and-answers/item/rad....

    According to the article it’s purely about heat: > The EU's standards note that within a phone's typical frequency range, the main danger of excess radiation is not changes to cells or chemicals in the body, leading to cancer, but "whole-body heat stress and excessive localized heating of tissues." The vast majority of mobile phone research indicates no adverse effects from regular exposure to the non-ionizing frequencies phones use to communicate. I can’t speak to why the chart has frequency dependent limits.

      Because EM radiation heats up body tissues! Heating is the main biological effect of the electromagnetic fields of radiofrequency fields. In microwave ovens this fact is employed to warm up food. The levels of radiofrequency fields to which people are normally exposed are very much lower than those needed to produce significant heating. The heating effect of radiowaves forms the underlying basis for current guidelines. Scientists are also investigating the possibility that effects below the threshold level for body heating occur as a result of long-term exposure. To date, no adverse health effects from low level, long-term exposure to radiofrequency or power frequency fields have been confirmed, but scientists are actively continuing to research this area.
