You can't say something is right or wrong because of statistics which could be fake or not. The truth is people will lie whenever they can if it helps them in any way. Also theres a natural radioactivity which is very different at each place and even there its different each day etc ...
My granddad worked in an uraniummine and he died when I was 3 months old. My other granddad worked in a carbonmine, he died when I was 15. Ofc you wont have carbon only in the ground, just because people want to mine carbon there. Radioactivity kills us, nobody is resistent against it. While some mushrooms that contain some substance actually grow faster and bigger with the help of radioactivity. The whole thing is just too big and scary to be understood by humans and in my opinion we shouldnd fuck around with.
Who doesnt believe that it kills you could just try it himself and go inside the reactor in chernobyl or fukushima. As soon as the radiation is high enough you will die - instantly.
So please stop telling people its harmless ... it's not !
