I think they are referring to Uranium with natural isotopic abundance. Which is complete bullshit when you put a picture of a nuclear power plant behind it – which in most cases can not function with the natural isotopic abundance (heavy water reactors being the exception, not the rule).
Depends on the isotope, of course. There are different ways it can hurt you.
If you put together a critical mass of ²³⁵U, it undergoes fission and you die in seconds without needing to ingest it.
Naturally ocurring uranium (²³³U-²³⁸U, mostly ²³⁸U) has a half-life of billions of years, so it’s very weakly radioactive. It would take a lot of it to harm you from decay radiation. Or very little if you pick a very unstable synthetic isotope outside the 233-238 range (but every element “has” such radioactive isotopes, though not in nature).
Uranium is chemically toxic, which is whal will kill you if you ingest a small amount of a common isotope.
I can ingest nearly 10g of uranium and not die?
Interesting.
