Xenon

Incidentally, the ability of Xenon to form compounds, under certain
conditions, was discovered when I was in graduate school, in (I believe)
1961, but those conditions are certainly much more stringent than the
conditions found in the ambient evnironment. Generally, ideal gases would
be trapped by van der Waals forces, not even by the weak chemical bonding
that binds some molecules to surfaces.
Ruth, besides clathrate formation, it has been known (since 1962) that
xenon like other noble gases are capable of forming ionic or covalent bonds
with highly reactive elements such as oxygen or fluorine.

Back to Commoner: the projections of nuclear power in the late 1970s,
coupled with the ideal gas behavior of Kr-85 and its yield in controlled
fission, could have been projected at that time to produce significant
exposure from skyshine and groundshine. It is NOT a question of
inhalation, but more of groundshine and especially skyshine. The skyshine
dose conversion factor for Kr-85 is significant. In fact, I believe one
might say that the lack of observed health effects from Kr-85 in the
atmosphere shows that the LNT does NOT apply. PLEASE NOTE: that is my
speculation alone -- no one has come up with this idea as far as I know
(and no, I haven't surfed the web to find out).
Ruth, have you ever seen any predictions concerning the annual dose from
the skyshine related to xenon?
