That is a good point and worth looking into. Personally, I would be surprised if the granite in WTC 7 were even enough to raise the ppm uranium of WTC 7's dust alone, to 7 ppm, but that could only be determined by finding how much ppm uranium that particular granite contained and then doing the math with regard to it and the other materials and contents of WTC 7. When the twin towers enter the calculations, I think the figure of 7 ppm uranium would be out of the question.
But you have made a good legitimate point, which begs further examination.
One reservation that could be raised almost immediately though, is the question of how much granite was turned into dust? Photos of the rubble of WTC 7 show a lot of the granite still intact. If very little of it turned to dust, then it would have a negligible effect on the ppm uranium of the WTC dust.
