Radioactive particles from nuclear testing are in every organism too. Just because something exists doesn't mean it's a disaster. You'd need science to back up a feeling like yours otherwise you're probably just regurgitating what popular opinion has indoctrinated you with and that's whatever's widely emotionally satisfying to believe.

Oh sure, I'm just speculating. But if you always waited for concrete evidence to conclude that something might be a risk, you would have may have been wearing hats coated in mercury in the 19th century, and eating of uranium-infused plates in the early 20th century.
