In the aftermath of the collapse, a team of scientists from the
US Geological Survey collected samples of dust from 35 locations in Lower Manhattan where it had come to rest
from the enormous pyroclastic dust cloud that enveloped the city.In the dust, they found high levels of chemical elements that had no business being there.
Extremely rare and toxic elements.
Some of them elements that only exist in Radioactive Form.
Elements such as
Strontium, Barium, Thorium, Cerium, Lanthanum and Yttrium.
The concentrations of these rare elements in the dust samples were related to each other by significant mathematical relationships.Although these elements discovered in high quantities are very rare in the general environment, one well known situation occurs in which they are very common. In fact, the elements discovered form a distinctive signature and hallmark of a certain well known chemical process.
