Where is americium found?
Americium is a highly radioactive element that can be found in a trace amount in Uranium minerals probably. Trace amounts can also be founds in places where nuclear tests were conducted. Small quantity is produced in the nuclear reactors mostly Americium-241 and Americium-243 isotopes. It can be produced in a 60-inch cyclotron which was first used in its preparation at the University of California, Berkeley.
