Now
after
we
have
a
preliminary
site
selection
then
the
fifth
criterion is that the field measurement confirms at a reasonable level that
cesium is,
indeed, present at that site.
And finally, a sixth criterion
that is very important is that the soil sample is collected successfully.
Howard talked about several different kinds of problems.
I think the worst
problem is that there might be a serious problem of crosscontamination of
samples; that the hole sloughs off, and you get relatively high activity
material that falls down and contaminates the lower levels.
So that if the
soil sample is not collected successfully, that's reason for rejection of
10 that site.

This shows our current results
12 in terms of numbers.
We started out with 105 desired communities, target
13 communities,
will,
if
you
that
we
felt
it
was
desirable
to
include.
14 Frosty's people went out, and according to my tabulations, selected 316
15 candidate sites attempting to look at more than one site within each
16 community, so that we had more than one choice if we encountered other
17 kinds of problems.
Actually measured by field spectrometry were 276.
On
18 the basis of those numbers, if we had three sites in a small community, and
19 they all had the same flux, then we only chose to, say, sample one of those
20 sites for soil; so that there was a considerable reduction in the total
21 number of sites that were actually selected for soil sampling.
22
In our present process now we've gone through, we had a target of 100
23 sites, and we actually selected 102 sites for lab cesium analysis.
Four of
24 those are questionable in terms that they need further verification; so
25 that we may have 98-102 sites depenc.ng on how those verifications turn
26 out.
That's mainly verification from somebody who will say that in their
27 memory that site has, in fact, been undisturbed since 1950.
