appear to be the critical criterion (such as later times after detonation than considered here), it would be necessary to make a more
precise evaluation.
Unequal distribution of isotopes in the bones has been observed.
Thus, the dotted line in Graph Five is included to suggest a possible
larger dose to those regions.

Considerable data have been collected on radiation produced bone
cancers.
One summarizing statement is me Visible changes in the
skeleton have been reported only after hundreds of rep were accumulated
and tumors only after 1,500 or more." 27
When one examines Graph Five
and reviews the data on doses and effects to the gastrointestinal tract
and possibly children's thyroids, it would appear that doses to the bones
is not the critical factor for the times discussed here.

Summary
Table Six summarizes some possible biological effects from radiation doses.
Due to inherent uncertainties in such analyses together with
expected wide biological variances among individuals, Table Six is
intended only to suggest a generalized picture of doses versus effects.
The physical calculations of radiation doses above were for
adults.

eTTees.
For equal intakes of radioactivity, children probably would
receive higher exposures due to the smaller organ masses, and in the
‘case of bones a greater deposition would be expected.
On the other hand,
increased turnover of iodine in children's thyroids might eliminate these
