    @oldclumsy_nowmad @futurebird I was going to look it up myself but realised the futility of it. IEEE is not a military organisation and real military standards tend to start with MIL, I think. Even if not, that whole line at the bottom screams fake.

    @muddle @oldclumsy_nowmad @futurebird IEEE 299 is about standard measurement practice

      @futurebird @oldclumsy_nowmad @muddle RF *can* hurt you if its high enough power, but that’s generally limited to labs and microwave ovens, not what’s emitted by cell phones

      …or anywhere outdoors. you might get a sunburn

        @muddle @futurebird @oldclumsy_nowmad the FCC limit on 2.4GHz transmitters is 1W for sufficiently spread-spectrum devices (including WiFi). The maximum emissions in any particular direction are capped at a level equivalent to a 4W omnidirectional antenna (this equivalent measurement is called EIRP). Most wifi devices operate well below that level since it's rough on battery life.

        Microwave ovens are limited by FDA to leaking a max of 5mW/cm^2 from any point on the oven's surface (measured 2in away). That works out to be a little below the power density you get from a worst-case WiFi transmitter at 3 inches away.

        The 99.7 number is the claimed shielding performance of the hat, not any regulations.

        @adrake @futurebird @oldclumsy_nowmad ah, I misread what you said about 99.7% initially. I didn't realise you were talking about the hat. So I guess I overestimated the effectiveness of the shielding and, hence, also overestimated the leakage

        I also did look up some more reputable info on max wireless tx power and was surprised to find that in some countries it can even go up to 4W (which tallies with what you said):

        Taken together, wifi and ovens seem to be roughly comparable rather than there being the orders-of-magnitude differences that I expected (with ovens emitting more radiation).

        Thanks for the correction. I guess I'll have to retire my "but microwaves leak more energy" argument when dealing with (literal) tinfoil hatters...

          Now, I'm not in favor of spam / scam callers...

          But, I somehow feel less bad about the idea of someone selling snake oil brand snake oil clearly labeling the contents as snake oil (even if there are some outlandish claims) and letting fools and their money be parted?

            I'm interested in noise pollution and light pollution. Light pollution is horrible for insects. (and birds) Noise pollution is bad for people.

            We could have less loud, dark at night (but still safe) cities and towns.

              @burnitdown @futurebird Its also interesting that different parts of the body are affected differently by microwaves. One of the more vulnerable parts are the eyes. So don't watch the food cook...

              @SamanthaJaneSmith @futurebird the shielding is there so you don't cook yourself at all. without it, you would need to stand dozens of metres away to operate the microwave.

                Do you think the people selling this are laughing at their customers or are they into it?

                It's like a damn joke.

                @futurebird They're selling it for $88? If they're not laughing, they're seig heiling at trump rallies.

                  @muddle @futurebird @oldclumsy_nowmad I think it's not accidental that they're comparable. Both are expected to be used by the general population with no safety training, so both should have limits that are safe under most circumstances.

                  Licensed users have different rules. Amateur radio operators are licensed to transmit at up to 1500W (!) on most of the 2.4GHz band, but they take on the legal burden of ensuring that whatever they do doesn't expose others to unsafe levels of emissions.

                    Sounds like a scam.

                                    @futurebird lol!

                                    the fact somebody made a tinfoil hat look legitimately cool blows my mind.

                                        I went on Facebook (I know I know I know) and they are selling tinfoil hats.

                                        The "Wavestopper" costs $88 Free Shipping!

                                        (I checked. It is not an April Fools joke. Selling to people with "brain fog" feels a little predatory to me.)
