Actinium Kids T-Shirts

A transcendent Actinium design. Actinium is a radioactive chemical element with symbol Ac (not to be confused with the abbreviation for an acetyl group) and atomic number 89, which was discovered in 1899. It was the first non-primordial radioactive element to be isolated. Polonium, radium and radon were observed before actinium, but they were not isolated until 1902.

Ac is the periodic table element symbol for actinium.

The orbitals are swirling in Storistir to make holiday ornaments! Actinium, element 89, leads the Actinides (elements 89-103). Actinium is naturally found in trace amounts in uranium ore, and was first extracted in pitchblende residues.

The actinides are not only radioactive, but they have been used in warfare. Little Boy was an uranium bomb dropped on Hiroshima and Fat Man was a plutonium bomb dropped on Nagasaki.
