while all electromagnetic radiation, including radiowave, microwave, infrared, visible light, UV, x-rays, gamma-rays, has common properties, the massively differing energies make it behave very differently.
and that means the energy per photon or minimal unit of radiation.
microwaves and x-rays for example have at least a factor of 1 million between them.
one main effect is that below UV and x-rays said radiation will mostly just heat up body tissue and while that can be bad mostly the heatup is low and you just don't care.
x-rays and above can knock stuff around at a molecular level leading to cancer at very low total power outputs. so they f you up long before they cook you.
and then x-rays and above also don't get stopped by metals as stuff below does.
aluminium foil will happily stop anything below x-rays.
so while mobile phones and microwaves might have negative influences on living tissue apart from heating it up a little bit we have not seen a lot of evidence of that.
x-rays and atomic bombs: ionizing radiation
pretty much everything else: non ionizing radiation
of that everything else ultraviolet is the highest energy still being able to destroy your skin without ionizing it ;P
weather radar even walking through the beam should not be a problem. it needs time to cook you
and that's what it would literally do if you stood there long enough. but don't count on feeling it either because we are used to heat coming from the outside so we feel heat only on the skin.
but microwaves cook you evenly more or less.
