Two populations were examined, the first being
children in Utah and Nevada who lived in areas exposed to fallow from testing
in the 1950s, and the second, other children fran the same states am! fran
Arizona, who were cons{dered unexposed.
Tamplin and Fisher, whose 1966 report
fs cited by Rallison et al. (1974), retrospectively calculated average doses to
al} children in Utah between 1952 and 1955 to have been 46 rads (maximum dose =
120 rads).
Later Mays, cited by the BEIR III report (NAS, 1980), estimated the
average dose for exposed children to have been 120 rads, ranging from 30 to 240
rads.
There was, however, no significant tncrease in thyroid neoplasia in
exposed children when compared to the unexposed children.
Benign thyroid
neoplasms were found in 6 of |,378 exposed subjects and in 10 of 3,453 unexposed
cortrols.
No malignancies were found in the exposed group whtle 2 were found in
