Wouldn't a better measure be radioactivity by the origin geography of food sourced? I can't imagine they sampled carrots from around the world and determined there was no stat sig difference. Growing carrots in Bikini Atoll is probably worse than carrots in Amazonian jungle.

"All organic matter (both plant and animal) contains some small amount of radiation from radioactive potassium-40 (40K), radium-226 (226Ra), and other isotopes"

Would this factoid be true pre-1945 Oppenheimer / Los Almost test? Because the world powers have carried out close to ~2056 nuclear detonations since 1945.

Yes - K-40 is primordial and Ra-226 is part of the uranium series from U-238, which is also primordial.
