What makes microwave radiation harmful to humans, while infrared radiation and visible light is not?

radiation with higher frequencies, like uv radiation, x-rays, and gamma rays are harmful, but infrared and visible light are not. so then why is microwave radiation, which has an even lower frequency harmful? also, what sets radio waves apart from microwave radiation to make them not harmful?What makes microwave radiation harmful to humans, while infrared radiation and visible light is not?
All radiation is dangerous if there's high enough power. People can be cooked by standing on a radio tower when it's operating. Once you're far enough away from the tower, it becomes safe because the energy is spread out over a larger area. The same is true for all other types of radiation (you can be burned by bright enough lights, or heat lamps for example).



Microwaves (as in the kind used in microwave ovens) are dangerous because water molecules resonant at those frequencies. What that means is that as you pump microwaves into water, the energy is almost completely absorbed by the water, instead of passing through the water (like visible light for example). The energy dissipates only because the molecules collide into each other from oscillating so violently. This causes heating, which is how microwave ovens work. The problem is that humans are made up of mostly water, and so microwaves can heat us up much quicker than exposure to infrared or visible light for example.What makes microwave radiation harmful to humans, while infrared radiation and visible light is not?
Do we really know? The meat companies and the people who make infrared radiation will tell us it is not harmful and do supposed 3rd party testing that they fear will lose them as a client and favor the bad company. So it probably is dangours. I think it is.What makes microwave radiation harmful to humans, while infrared radiation and visible light is not?
A good question. You can feel infra red radiation as heat, but you can't feel microwaves or radio waves. So when the IR radiation is intense enough to harm you, you get out of the way. Microwaves can cook you without any warning pain, and they penetrate deep into your flesh, unlike IR. Radio waves can cook you too, but they're much less likely to than microwaves because your body absorbs them much less efficiently. But it would be a bad idea to get too close to a powerful broadcast transmitter. The microwave frequency which your body absorbs most efficiently is 2.45 GHz, which is the frequency produced by microwave ovens. It is also one of the frequencies produced by radar, such as weather radar. I used to work with radar systems, and I heard plenty of horror stories about things that went wrong. Planes which carry it have a safety device which disables it when the undercarriage is down, so it can't operate it when the plane is on the ground.
