There's no real indication of super-sensitivity in individuals, which is, I think, what you were suggesting with the one person in a million. If we'd had super-sensitivity in people, I think it would have been identified by now, because, as I said, there are a huge number of people who are exposed to quite significant amounts of uranium in the world. It's a common thing. Everybody has uranium in them.
With regard to the treatment, it's not really very amendable to that. If you have uranium in the body, it's one of the materials that are difficult to remove. It gets deposited in the skeleton.
