Is Uranium dangerous?

The M.P for the green party Keith Locke urged pacific countries to stop mining uranium as it is dangerous.

Here is his statement from the web page Radio NZ

But Keith Locke says uranium is very dangerous in any form.

“I think we should discourage Niue from allowing this form of exploration because we don’t want Pacific countries involved in uranium mining. And there’s a big controversy in Australia right now about the export of uranium to countries like China, where it might be used to make nuclear weapons.”
