Yeah but uranium kills you after a bit, kryptonite takes him out instantly.

    If that was the case, Superman would have died more than once.

    I only know of 1 time and kryptonite wasn't even used. Doomsday just beat him to death.

    Depending on the writer, there are three consistent kryptonite types:

    Green weakens him, but overall it doesn’t kill him. Strips his powers, makes him faint or just weak and nauseous.

    Blue just takes his powers away either temporarily or permanently

    Red intoxicates him or enhances his impulsiveness/brashness

    There are others, but they kind of shift of just don’t exist in the main canon

    Arsenic and mercury, both commonly occurring metals present in rocks, can kill humans immediately. Especially if vaporized. Uranium can kill and disable quickly in high enough concentrations.

    Also, keep in mind it's a plot device about a fictional flying space alien with laser eyes. It doesn't need to follow the laws of physics.

    But then they’re not rocks. It’s a vapor or a metal. That also actually disqualifies uranium as well since the rock isn’t what’s dangerous, it’s the radiation that destroys your cells. With Superman it’s literally just a rock.
