The number of particles that can be resuspended from

These experiments have usually resulted in the determination

that,
"reported
[RF]

for plutonium
range over 11 orders of magnitude."
This
11 orders corresponds to values between 1071 to 107ll ml.
Kathren indicates
that,
"an RF of 1074 ml,

The Thule Deliberations refer to the deliberations following the accidental
crash of a B-52 bomber carrying nuclear weapons near Thule
Air Force Base in Greenland.
The high explosives in the
weapons detonated and dispersed the plutonium.
