As uranium and thorium naturally decay underground, they produce some helium as well. That’s why you can literally make a helium mine. On earth it’s also a finite resource, because once released into the atmosphere, it will eventually escape the atmosphere and end up in space.
Helium is not toxic and it sure as fuck isn’t going in the ocean after it escapes a quantum computer.
It’s also one of the most abundant elements in the universe
But it is difficult to acquire here on earth.
