I think the "1000+" is a little misleading, so to clarify: longer half-life means less dangerous, something like unrefined uranium has little radiation risk unless you have very long-term exposure to it (but it's very toxic because it's a heavy metal, so it will still kill you), its half life is billions of years, something on the order of magnitude of 1000 years, like Radium, is way, way worse.
