Yellow and white
The fallout particles collected following low-yield
surface shot in Nevada consisted of glass derived from
melting of silicate minerals of soil. The fallout particles were transparent spheres of yellow-green color,
irregular opaque grains brown in color which did not
differ in appearance from unaltered mineral grains of
original soil.
Fused particles are most important from standpoint of
activity. Common feature is that at least one side of
every particle is clear,
tints.
glassy material with green
The fused material contained gas bubbles.
The
particles which contained no activity but contributed
most weight are yellow, opaque, oblate spheroid and white
opaque.
,
Particles from underground shots were irregular in shape
and opaque in appearance.
Particles appear to be fused
earth with adhering small metallic points and imbedded
black specks.
(1-4)% of particles are glassy spheres
(transparent, either colorless or blue-green amber).
Occasionally one finds black pitch appearance.
Few glassy particles exhibit teardrop shapes.
Most
radioactive particles are irregular shaped, white to
grey, translucent to opaque.
