And they are not talking about radiation from evolutionary sources but manmade sources and waste here; so don't start with that argument. We're talking about exposure to persistant artifical sources of radioactivity here.
Radiation is radiation. A gamma with a certain energy is exactly the same as any other gamma with that energy. There aren't "natural, organic" alpha particles that are better for you than "evil, artificial" ones.

Nuclear power is hardly 'clean'. The mining and refining processes are very energy intensive and produce vaste quantities of pollution. We have NO way of safely disposing of the mulitple toxic waste streams involved with nuclear power (and you cannot separate nuclear power from nuclear weapons).
Just tell me again how 'clean' an energy source nuclear is. Just how limited is your definition of 'clean'.

Nuclear energy is the cleanest power source we have right now, provided it's maintained and built correctly. Fossil fuels are killing this planet.

UV is UV, whether from the sun or an arc light. What matters with UV is the wavelength not its origins. X-rays are a much more energetic wavelength and cause more damage. However, solar x-rays behave just the same as "artificial" ones, wavelength for wavelength.

Yes. But, for example, our skin 'tells' us when we've had enough sunlight by responding with a sunburn.
