What is the main use of protactinium?
That was the world’s only stock of the mental for many subsequent years. Currently, protactinium is usually extracted from used nuclear fuel. Due to its scarcity, high toxicity, and high radioactivity, protactinium has no current practical uses other than basic scientific research.
What does protactinium mean?
: a shiny radioactive metallic element of relatively short life — see Chemical Elements Table.
Is protactinium man made?
Encyclopædia Britannica, Inc. All 29 isotopes are radioactive; synthetic protactinium-233 is produced by neutron irradiation of thorium-232 after it is converted to thorium-233 and is the progenitor of the fissile uranium isotope uranium-233 in the production of nuclear fuel from thorium.

Does thorium occur naturally on Earth?
Thorium (chemical symbol Th) is a naturally occurring radioactive metal found at trace levels in soil, rocks, water, plants and animals. Thorium is solid under normal conditions. There are natural and man-made forms of thorium, all of which are radioactive.
Why is thorium dangerous?
Thorium is radioactive and can be stored in bones. Because of these facts it has the ability to cause bone cancer many years after the exposure has taken place. Breathing in massive amounts of thorium may be lethal. People will often die of metal poisoning when massive exposure take place.
