I thought X-rays do not pass through metal? Like it shows up opaque in clinical images. Suprised that they got a scan of the moka pot. Truly amazing stuff.

  Metal blocks some x-rays but not all. The more x-rays you have, the more pass through. When doctors are xraying people, they use as little xrays as they need to get a good image of the fleshy bits, so metal objects appear opaque relative to that.

  You can use a much higher dose on inanimate objects than you could on a human patient. (See, for example, airport security's ability to see inside your Macbook...)

  X-rays are used a lot in non-destructive testing for welding and also in civil engineering to look inside concrete and rebar!

  Entire aircraft engines and rocket engines can in fact be x-rayed (google image search awaits you). Granted if you stuck your hand in there it would definitely get cooked. The power levels are much higher. If you really want to dive down a rabbit hole, look up how they image welds on pipelines... literally inject radioactive gas between two cardboard/clay plugs and tape an xray film on the outside of the weld for an hour or two.
