No. Well, if you try to walk on one, you'll fall through, and that would hurt......

Not unless one falls on you.
Radio telescopes don't transmit anything. They are super-sensitive receivers, designed to
pick up the faint whispers of radio signals coming to earth from elsewhere in the universe.
Your cellphone exposes you to more radiation than the largest radio telescope in the world does.
Cosmic rays are not "rays" at all, but high energy charged particles that arrive at our Earth from somewhere "out there" -- their precise origin is presently unknown.
Like any high energy charged particles, cosmic rays carry some potential for biologic harm. For most humans on the surface of our Earth, the risk is minimized because (1) the particles lose most of their energy when they blast into the upper atmosphere and (2) most particles follow the magnetic field of our planet towards the poles. Thus, the degree of "danger" is comparable to that from decay particles of radioactive material in the rocks around us.
For people who leave our Earth for long term space travel, the danger is increased, but the degree of such increase is difficult to determine.
Radio telescopes are basically specially designed antennas. They don't "see" anything. They "hear".
Telescopes are not dangerous in normal operation. A large telescope might hurt you if it fell on you.
no, reflecting telescopes.
Not necessarily.
Yes, that is correct.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
No they are not bigger then radio telescopes at all.
Radio telescopes gather data from radio sources and they target the radio frequency part of the electromagnetic spectrum.

using radio waves it collects the data.
