Polonium in tobacco smoke

The presence of polonium in tobacco smoke has been known since the early 1960s. 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. Radioactive polonium-210 contained in phosphate fertilizers is absorbed by the roots of plants (such as tobacco) and stored in its tissues. polonium-210, which emits alpha radiation is estimated to cause about 11,700 lung cancer deaths annually worldwide.
