One aspect of this discussion about Cs-137 uptake as it relates to
weapons testing fallout is that not all of the fallout Cs-137 was
readily available for uptake in that it was bound to particles.  If I
remember correctly, there was a paper in Science back in circa 1961
which stated that about 40% of the deposited Cs-137 was tied up in
particles/bomb debris from which it was not immediately available for
biological uptake.  Does anyone know whether the similar fractionation
occurred in the Chernobyl debris?
