Ionizing radiation IS a specific thing, and radio and microwaves dont do it.KnightoftheRoc wrote: "Radiation" is a misnomer. It's not a thing, it's an action. Radiation is the projection of highly charged particles away from the originating source. Some highly charged particles act like waves, some act like particles- light is a great example of a form of radiated energy that displays aspects of both particles and waves- enough so that Science has not yet firmly nailed down exactly which column to list photons, particles or waves. Microwaves are NOT "radio waves", they are a higher section of the EM spectrum, and we sometimes use them to carry signals, like cell phones and wifi. The difference there is in the intensity of the signal strength, as opposed to a microwave oven. Both cell phones and microwave ovens use frequencies in the microwaves range of the spectrum, but the signals emitted differ greatly in amplitude, or strength. A comparison between them could be likened to an old train set transformer, and the wall outlet powering it- both use 60Hz AC voltage, but the outlet provides much more than the transformer. Radio waves cover the EM spectrum from the Khz (thousands) to the Mhz(millions) frequencies, inclusively, microwaves are in the Ghz (billions) frequencies.
Sorry about your pal's brain tumor, but the plural of anecdote is not data.
And no, I'm not going to get into a fight with you about milliwatt EM being dangerous.
