answer:Microwave radiation is non-ionizing, this means that other than heating you up, it’s not going to cause cancer or other long term issues. They’re also well shielded, so the leakage from a microwave isn’t going to really cause any stronger effects than, say, a cell phone across the room. I wouldn’t stick my head in one, but that’s because I’d prefer the enzymes in my head didn’t get denatured by the heat.
