How might the present study be expanded to obtain
additional information?
a)
The following plan is suggested:
The fallout deposition should be established
for each one of the Nevada test shots.
The
actual deposition of fallout should be evaluated
by records of field gamma-ray intensities and
fallout tray beta-activities, when available.
When measurements are lacking, the deposition
on the ground should be estimated from
meteorological considerations.
kcological
factors could have caused the doses to the northern
part of the state to be materially higher
than calculated for the early tests.
Rainfall
is greater in northern Utah, and rain brings
down fallout from the air.
Also, the studies
of Pendleton have shown that plant uptake is
higher from wet pastures than from ary.?
In
the 1962 incident, the highest levels of
iodine 131 observed in Utah milk were not in
the south-west and central farms first traversed
by the fallout; the highest observed levels
were in the north-east portion of the state,
over 400 miles from the Nevada test site.
b) From feeding practices, the transfer of
iodine 131 to milk should be estimated for each
milkshed.
Very little iodine 131 appears in
milk when the cattle are on aged stored feea,+
as, for example, during the winter.
Special
efforts should be made to eStimate the iodine
131 levels in the nilk of those dairies which
supplied large populations.
c) The populations served by the major dairies
should be identified and recorded.
Dose
estimates to these populations should be made,
and the povuletions classified into rradec
dose levels.
