Funny you should mention a microwave, because that's basically your RF on steroids. And a microwave, if you were put inside one, would simply burn you up completely. No matter what level it's at, there's simply no evidence to show that it does anything damaging at the molecular level that gamma/x-ray radiation does; let alone even ultraviolet. And you're exposed to that everyday.Interesting that many states now have cell phone radiation laws and are requiring manufactures to list the amount of radiation the phone transmits.
If you think about it a cell phone transmits higher levels of radiation than say a walkie talkie. Which at the toy level is not harmful, but the military grade could be.
And I would no more place my face on the door of my microwave oven while it is cooking, than I would keep my cell phone plastered to my skull all the time.
They used to say getting x-rays or CT scans weren't harmful.
I'm just saying.
Now, if you want to talk about extremely frequent exposure over a decade, that's totally different. Even then, there's not much data to suggest a causality even in that circumstance. You probably have a better chance of getting cancer of the bowel from drinking a liter of diet soda a day.
