Is protactinium man made?
Plutonium is a radioactive metallic element with the atomic number 94. It was discovered in 1940 by scientists studying how to split atoms to make atomic bombs. Plutonium is created in a reactor when uranium atoms absorb neutrons. Nearly all plutonium is man-made.
Is protactinium radioactive?
A silvery, radioactive metal. Protactinium is little used outside of research. Protactinium has no known biological role. It is toxic due to its radioactivity.

It is against the law in the USA for any private citizen to possess or transport a”destructive device.”
How much does a gram of plutonium cost?
It costs around $48 per gram. Plutonium is a radioactive element that can be used for research and nuclear applications. It’s worth about $4,000 per gram (although you can expect various regulatory agencies to take a close look at you if you start accumulating it).
Which element is most costly?
