Actinium exist in all uranium minerals: ex. uraninite (pitchblende).
Batteries doesn't contain actinium.
Actinium is found in uranium and thorium ores.
Actinium is found in extremely low concentrations in residues from uranium ores (uraninite, pitchblende).
Discoverers of actinium: Andre Louis Debierne - 1899 Fritz Giesel - 1902 Actinium is found in uranium minerals.
Actinium exist in minute traces in uranium and thorium ores.
Actinium exist in minute traces associated with uranium or thorium ores.
Actinium is found in very low concentrations in uranium ores, probably as an oxyde.
Actinium is separated from pitchblende. Actinium, AC, is found in uranium ore, a product of radioactive decay of uranium and ?æother unstable elements.
in 1899 in France.
Probably all actinium prepared in the world in the last 125 years does not exceed 100 g !
From Wikipedia "Actinium is found in trace amounts in uranium ore, but more commonly is made in milligram amounts by the neutron irradiation of 226Ra in a nuclear reactor. Actinium metal has been prepared by the reduction of actinium fluoride with lithium vapor at about 1100 to 1300°C."
Actinium is a radioactive metal; no taste !
