Actinides in the environment, a Common card

The card carries these facts from its Wikipedia article.

• The nuclides thorium-232, uranium-235, and uranium-238 occur primordially, while trace quantities of actinium, protactinium, neptunium, and plutonium exist as a result of radioactive decay and, in the case of neptunium and plutonium, neutron capture of uranium.
• These elements have much shorter half-lives than the naturally occurring thorium and uranium, and thus are far more radioactive.
• Elements with atomic numbers greater than 94 do not exist naturally on Earth, and must be produced in a nuclear reactor.
