Now, from January '54 through to
about April, 1955, we were running between
14D per quart to 2 to 3D per quart in powder-
ea milk and then in April, or sometime be-
tween April, May and June, we evidenced a
very distinct riee in strontium 90 content.
We felt this was quite real,
TI
might point out that our analytical error is
2 tenths of a D per quart, That also, backed
up by our evaluation, this is a real rise,
.
Furthermore, ve analyzed some of
these milk iteme for other strontium Lsotopes,
strontium 89 and we received extremely high
89-90 ratio during this period, whereas
through here, the 89 level was extremely well
below strontium 90,
This backed up our assumption that
_ this rise very probably was due to Teapot, This
was during the grazing period and then around
August and September, we presumed that most of
the grazing animale: are indoors because after
August, we did not discover a distinct drop off.
As a matter of fact, it was very hard
for us to discern whether there was an increace,
a levelling or a decrease because we obtained
quite considerable variability,
In our eligible
