I don't know, but I think that for any reasonable forces—in the absence of the device that you and Mr. Stoffer will be working on and get rich with—the only improvement at this time would be, in a given situation if there is a reasonable chance of exposure, let's say to depleted uranium or something else, to get those measurements, urinalysis in this case, as soon as possible because the longer you wait, the less reliable your result is. That is the one thing.
From a technological point of view, I don't know where the Americans are. They're probably working on it, though.
