But isn't radiation all around us in the nature as well? As far as I have read they even use radiation to "mark" the gulf stream to measure it's movement. And what about the radiation coming from cole mining?

But maybe you are right and every dose of radiation even the one from the sun kills us over time. I mean, the skin of older people is not as clean as the one from young people. There are growing a lot of dark spots and bumps. Maybe this is life. Maybe it would be better to have fur like animals have.

I dont judge anything here, I just think out loud.
