This is worse than an LQD. This diary is simply a question.
What is the influence of atmospheric nuclear detonations, greater than 2,000, AND the sum total of accidents (accidents?), on measurement of background radiation?
We know about radon (at least somewhat), and we know about bananas, and current knowledge of potassium isotopes in the body. We know that flying gives us x, and dental or chest x-rays give us y or z.
But do we know what normal background radiation is? Is there any data which shows change in background radiation from civilization?
I won't list all the places that are leaking since the late 40's. I'm only wondering.
I'm not inclined to disparage arguments of normal background radiation, like everytime you fly x km. I'm even willing to entertain the notion that living on a planet which exists in deep space has some attendant risks.
I'm just wondering how we know what background radiation is, and how we came to that knowledge. Can i get some help?
