    You don’t need iodine, this isn’t going to give you radiation sickness, but it is a little surprising.

    From a WaPo article:

    France’s digital minister said the iPhone 12’s radiation levels are still much lower than those that scientific studies say could harm users, and that a software update could solve the compliance issue. The ANFR itself acknowledges that its tests don’t reflect typical phone use.

    Which links to:

    The @anfr found that the iPhone 12 was emitting a level of waves slightly higher than the authorized threshold.
    This level is more than 10 times lower than the level at which there could be a health risk.
    But the rule is the rule: Apple must comply.

    The wave levels that smartphones emit can vary during a software update. It is undoubtedly because of an update after its release that the iPhone 12 exceeded the authorized threshold. And it’s a simple update that will bring it back into compliance.

    The classic conditions of use: the real DAS

    Laboratory measurements do not reflect what happens during the usual use of the device. Indeed:

    • for voice communication, the phone statistically emits only about 50% of the time, the phone does not emit when listening; in addition, the average duration of a communication is less than 3 minutes;
    • for data-oriented use (internet or video), the durations of use are certainly longer; but the phone, which generally receives more information (videos, emails…) than it sends, rarely emits more than 10% of the time during the session;
    • the value of the DAS displayed in the points of sale corresponds to a precise frequency (e.g. 800 MHz) and technology (e.g. 4G) for which the maximum has been detected; but, in reality, the phone does not work permanently under these conditions: it often changes frequency or technology;
    • Finally, for all uses, the phone rarely emits at its maximum power, due to constant interactions with the network to best adapt to its conditions.

    The real SAR therefore does not often coincide with the maximum SAR.

    As the DAS is proportional to the power emitted by the telephone, it is possible to evaluate the actual DAS by measuring the power put into play by the terminal. This can be evaluated thanks to professional software installed on consumer phones

      That doesn’t change the fact that it’s not outputting ionizing radiation. It doesn’t change the fact that the phone would literally have to be emitting hundreds of watts in order to begin having a noticable affect on its surroundings. I cannot fathom that the iPhone is legitimately able to output any level of ionizing radiation as you’d probably need physical chips designed to do that (or have a phone made out of uranium).

      Most em radiation is literally harmless. Visible light is a form of em radiation. So are radiowaves and infrared. It’s all photons. The reason why some kinds of em radiation are dangerous is because the photons can damage physical matter. Here’s an image showing where the different EM bands are and what they correspond to:

      Anything above visible light (UV and higher) is ionizing and dangerous to public health. Anything in the visible spectrum and below is only harmful when emitted at a high enough quantity to blind or literally cook something. It’s only UV and above in which the photons have enough energy to damage physical matter.

        It’s not outputting ionizing radiation… nor is it outputting radio near the limits that are causing it to get removed from the market except under laboratory conditions where its being forced to operate at maximum power that the transmitter is allowed to (by the software) for extended times… which could get fixed by software… and is 10x under the limits that would theoretically be a problem under the levels that it was observed at… which is being tested at a much closer distance (inverse square getting in there) compared to other accredited laboratories in the EU (EU is up to 25mm, FCC is 15mm, France is doing 0-5mm) without changing the absorption levels to compensate ( https://www.anses.fr/en/content/exposure-mobile-telephones-carried-close-body )

        And France has been pushing a “beware of excessive cell phone use” for a long time. https://arstechnica.com/uncategorized/2008/01/france-beware-excessive-cell-phone-usedespite-lack-of-data/

        I was just citing the sources in France that was showing that this was taken a bit to the extreme. When you consider all the rest of it, it feels rather silly and Apple is likely doing a “whatever” and pulling a 3 year old phone from the French market.

        Most em radiation is literally harmless

        Sorry but that’s just not true. All radiation is harmful at high enough levels for prolonged periods of time. Sunlight, for example, will literally burn you in minutes if you’re near the equator and don’t have a tan.

        Microwaves operate at about the same frequency as cell phones and at a thousand watts or more they will turn your blood into gas with just seconds of exposure. That would be a very very painful way to die.

        The government has officially defined a power level that phones are allowed to output, and iPhones are outputting more than that. So they need to fix it. Immediately.

          Yeah, microwaves can do that. At hundreds of watts at least. The other articles I’ve read suggest that the iPhone is putting out less than 6 watts. Go look at how many watts your microwave uses to heat something up. Imagine how bright a 6 watt lightbulb is. That’s what we’re talking about. Your computer screen probably puts out more EM radiation than a fucking iPhone.

          That’s what makes them literally harmless. Yes, they can technically cook you, but only at ridiculously high levels. Compared to UV, which can cause skin cancer at lower levels, they’re harmless. Additionally, unlike UV, you aren’t running the risk that they’ll kill you with repeated exposure.
