They can be, if you're willing to put in the effort that it would require.
You must be slightly off-kilter to begin with, and then here are a few ways
it might be done:
-- Modify your microwave oven so that it can run with the door open. Then
stand in front of it while you pop the corn or heat the leftover meatloaf.
-- Set up your lounge chair, then relax with a drink and a good book, five feet
in front of a Doppler radar antenna. Stay there for a substantial length of time.
-- Take an office job at a popular FM radio station that serves a large geographic
area. Set up your office on a platform mounted on the tower, either at the top,
or, better, between two bays of the transmitting antenna.
Short of those efforts or similar ones, your attempts to do yourself harm
by means of radio waves are doomed to failure.
Probably very little; but it is probably more risky if you are close to the antenna. The jury is still out on the riskd of all microwaves____from infra red to ultra violet, xray, etc.
They don't. Radiowaves are not forms of ionizing radtion and therefore will not affect you.
The have no effect.

Yes. Radio waves are electromagnetic and are affected by anything that conducts electricity. The human body is mostly made of water, which conducts electricity and therefore affects radio waves. To demonstrate the effect, see what happens when you move around a radio tuned to a station with relatively poor reception.
The energy of a electromagnetic wave increases as the wavelength decreases. Radio waves have a very long wavelength compared to gamma rays. Since gamma rays have so much energy, they can change molecules by "kicking out" electrons with their energy. Where as radio waves don't have enough energy to effect many compounds.
no, mechanical waves are not radio waves
Light waves do diffract, but the effect is very very small. In general diffraction effects are important when the object interacting with the wave has dimensions that are comparable to the wavelength of the wave. Light waves have much shorter wavelength compared to the radio waves. Hence the effect. (It should also be noted that radio waves penetrate buildings much better than light waves, but that leads to a more nuanced discussion of diffraction effects.)

The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.

Transverse. Radio waves are electromagnetic waves, which are transverse.
To map body tissues, MRI (Magnetic Resonance Imaging) uses a combination of techniques: a powerful magnetic field, and radio waves. Radio waves are utilized for mapping because they will not damage the body tissue.
Radio waves (along with magnetism) are used for that purpose instead of x-rays in MRI machines. x-rays are absorbed by the body differently than radio waves, so it depends on what in the body is being looked at.

Radio waves ARE electromagnetic waves.
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
