In Joe vs the Volcano. Joe has to sacrifice himself to the Volcano so that billionaire investor Mr. Graynamore can get his hands on the islands natural technetium. This is interesting as Technetium (as the name implies) does not occur naturally. So, what is technetium and how it is produced?

In truth though, they have produced it in many different ways throughout the years.
Post War they exploded nukes out in the Pacific Ocean Line Islands and the Bikini Atoll which then created nuclear isotopes so that Scientists like Werner Von Braun and Trump's Uncle at MIT could play around with their X-Ray machines.
They then realized that these isotopes could be produced in a nuclear reactor. As soon as the first commercial reactors like Caldwell B in the UK came into production they stopped the nuclear testing as they didn't need to do it anymore to create the isotopes.
The creation of nuclear isotopes is the only explanation in my mind why the methodically set off nukes every few months in Bikini Atoll. It was because of the decay of these isotopes it had to run on a schedule.
