Under these circumstances it is reasonable
to assume that children drank the same amount of water and, therefore, had
rhe same intake as adults; i.e., their thyroid burdens were also 11.2 uc of
I (range 5.6 - 22.4 uc).
The most probable dose from 131, is then 490 rad and the total dose
1270 rad.
Considering a range in the thyroid burden (5.6 - 22.4 uc) and da
thyroid weight range of 1.9 - 3.1 gms, the range of total dose is 520 - 3300

tad.
Incidephglly, LASL assumed this mode of intake and calculated a dose
of 150 rad.
The thyroid weight used was not given but was probably 20
grams.
We would calculate 160 rad, in very good agreement with the LASL
estimate,

The actual intake was undoubtedly a combination of the two modes of
intake.
The most probable dose is, therefore, in the range 700 - 1400 rad.
