This sample has been taken
from a rough glass fiber filter in the central
heating system of an appartment
building about 500 yards from the crash
spot of the EL-AL Boeing.
This filter was designed
to keep the autumn leaves out of the building.
Behind this filter were heavy
ventilators which blow air into the natural gas
heater. Only occasionally
uranium particles are trapped in the filter. Most
uranium dust pass the filter
and will disappear in the fire. These particles
dissipate via the exhaust
in the open air.
This is a way of resuspension.
The uranium oxide particles can
later be inhaled subsequently
by practically anybody.
The result of the analysis
shows a minute fraction of U236 which is a
uranium isotope from a nuclear
reactor. Uranium 236 is always accompanied
by transuranes like americium,
plutonium and neptunium.
It can be expected there
is a certain fraction of plutonium, neptunium and
americium present in this
The high fraction of Uranium
234 is from the natural uranium portion mixed with
the reprocessed uranium.
