&s one sort of mild indication of the rage.
DR, BUGHER:
Just ae an exercise
in logic, we could arrue Just as well that the
whole sampling system of pots, gummed paper and
everything else, only apvreciates a fr-ction of
what actually is available to the eurface of
the earth or what fe bound to it.
I think
that variability of the ratio: shows that,
MR.-EISENBUD:
All it requires is an
ascurption of fractionation to say, a factor of
a little over two which is quite reasonable and
consistent with measurements that we meade here
in the laboratory which was actually recovered
and brought out on the air cloce to the test
and at a distance that we find more stpontium
on the test papers as we go out a distance,
As a matter of fact, two I think would
be quite reasonable because this factor of two
49 on top of 1.6 which would bring it up to
the 3.2 which is pretty oloce to the 3.8
But
I don't think we really know,
I mean, we cannot help but speculate
about these things,
