Ac was that intravenous injection of simple actinium complexes resulted in their accumulation in the bones and liver for a period of tens of years. en.wikipedia.org

Polonium-208 and actinium-227 were also considered as alpha sources. en.wikipedia.org

Actinium is mostly present in uranium-containing, but also in other minerals, though in much smaller quantities. en.wikipedia.org

For example, the alpha-decay of uranium-235 forms thorium-231, while the beta decay of actinium-230 forms thorium-230. en.wikipedia.org

Chemically, actinium is similar to lanthanum, which is explained by their similar ionic radii and electronic structure. en.wikipedia.org

Actinium has similar chemical properties as lanthanum and other lanthanides, and therefore these elements are difficult to separate when extracting from uranium ores. en.wikipedia.org

Secondary decay products of thorium include radium and actinium. en.wikipedia.org

When actinium trichloride is administered intravenously to rats, about 33% of actinium is deposited into the bones and 50% into the liver. en.wikipedia.org

Owing to its scarcity, high price and radioactivity, actinium has no significant industrial use. en.wikipedia.org

Ac one tonne of ore contains about 0.2 milligrams of actinium. en.wikipedia.org
