    If it’s contained in glass or something and not just an open canister of powder, it’s actual fairly innocuous

    You can take uranium rocks from the US and transport them in a commercial airline over the world.

      And you’ll be exposed to more radiation from being at cruising altitude than from the rocks!

      yeah because uranium actually decays so slowly that the radiation it gives off is barely worth mentioning. the actually hazardous stuff is what comes out of nuclear power plants spent fuel rods.

        Part of it is the decay frequency but also how it decays. Uranium238 does an alpha decay that can’t penetrate the glass

          It can’t even penetrate your skin

          As long as you don’t ingest it, you’ll be fine

          The decay products themselves decay through beta decay before arriving at a stable (at human timescales) U234 again. In the chain there is a bit of gamma radiation sprinkled in as well, but overall the decay chain, with the shielding provided by the glass, whatever other bedside obstacle there might have been and the probably small sample size should not have increased the obtained radiation dosage by a significant amount.

            I could be mistaken but doesn’t u238 go down the full alpha decay chain ending in lead206 albeit with a few random beta minus decays thrown in that also shouldn’t penetrate glass?

      Probably shouldn’t, though, unless you have a good reason for doing so.

        Look for thunderf00t on YouTube, a scientist who did exactly this. Went to the US to gather uranium rocks and took then back to the Czech Republic and he used them to grow and eat carrots to show that it doesn’t.do much, really
