Some, not all, radio waves.
The reflected ones are the ones used for short-wave radio.
It depends on the type of radiation. Alpha can be stopped with a few inches of air, or even a sheet of paper. Beta can be stopped with a sheet of metal. Gamma and neutron takes lead and/or concrete, sometimes several feet. Neutrinos can hardly be stopped by anything - they travel through the Earth with ease.
Not sure about it. But I remembered this layer of the atmosphere called the ionosphere or the thermosphere.
No, gamma rays are not stopped by an electric field.

The Ionosphere
Eletromagnetic radiation with a frequency below the ionosphere's plasma frequency will generally be reflected. The specific frequency depends on the density of ionospheric plasma which can vary at different altitudes, but also different geomagnetic latitudes and from day to night. For a typical daytime mid-latitude ionosphere, the most dense part of the ionosphere, (the "F" region), will reflect radio frequencies up to ~2.8Mhz (assuming an electron density of 1e11 m-3).
The thermosphere contains the ionosphere. The ionosphere is the layer that is ionized by the solor radiation.
The distinguishing characteristic of the ionosphere is that it is ionized by solar radiation.

Microwaves. These poke through the ionosphere to reach the satellite
# Radiation makes this zone ionized.
Gamma radiation
This is primarily the ionosphere that contains the ions.
The ionosphere exists because of the absorption of radiation from the sun. It is made up of electrically charged gas particles.
Beta Radiation
I assume you mean fission technologies as aftificial fusion is yet to work except under extremely controlled lab conditions. The answer is yes for fission power generation, fission is caused by the instability of large atoms. No ionizing radiation would affect the fission of atoms generating heat. However if a certain type of radiation was required (for certain medical procedures for example), it could not be preformed in the ionosphere except in a radiation shielded room because other radition types are present in the ionosphere.
