今天我发现了还有这个:
Tobacco

The presence of polonium (釙, 居里发现的,明名after Polish) in tobacco smoke has been known since the early 1960s.[96][97] Some of the world's biggest tobacco firms researched ways to remove the substance—to no avail—over a 40-year period but never published the results.[43]

Radioactive polonium-210 contained in phosphate fertilizers is absorbed by the roots of plants (such as tobacco) and stored in its tissues.[98][99][100] Tobacco plants fertilized by rock phosphates contain polonium-210, which emits alpha radiation estimated to cause about 11,700 lung cancer deaths annually worldwide.[43][101][102]
Food

Polonium is also found in the food chain, especially in seafood.[103][104]
