So far no one has shown Jones to be incorrect.
"Testing the Hypothesis that Mini-Nukes Were Used on the WTC Towers
author: Steven E. Jones
Empirical Facts: All nuclear weapons (especially FUSION/Hydrogen bombs) release copious high-energy neutrons which will activate steel and other materials. This is called neutron activation and cannot be avoided, and much of the induced radioactivity remains for decades.
I have studied fusion for decades, and have made frequent measurements of neutrons (as well as charged particles).
Several months ago, I tested WTC dust samples and a solidified metal sample for radioactivity using a Geiger counter: I found ZERO RADIOACTIVITY. This experimental evidence goes strongly against the mini-nukes hypothesis since neutron activation levels were zero.
I also tested some sand gathered from a nuclear-bomb test site decades ago for comparison – and the Geiger counter showed hundreds of counts per minute. This also shows the long life of the radioactive residues due to nuclear bombs – the sand still yields high Geiger-counter readings decades after the nuclear bomb blast.
Note that concrete pulverization is often achieved in controlled demolitions with chemical explosives, e.g., the Seattle Kingdome demolition.
Mini-nukes are not needed for pulverization nor for “top-down” demolition as observed for the WTC Towers.
