The estimates for 30 year whole body doses in the Survey Report are
summarized in Table 1, and 30 year bone dose estimates are summarized in

Table 2,

Note that the option for "Gravel Village Area - Plow Village

Island," achives a minimal reduction in radiation exposure of whole
body and bone for all living patterns, and those living on JANET would
have to import most foods to avoid exceeding a whole body exposure of
4 rems in 30 years.

Population dose guidelines used by the Task Group

include annual dose rates as well as 30 year intergrals for genetic

doses,

Tables 3 and 4 show estimates of the maximum annual whole bedy

and bone dose,*
In considering the reduction in exposure that may be achievable through
renoval of contaninated soil, the Task Group has taken the position that these
predicted exposures are approximations ocnilv,

The effeetiveness of such actions

to reduce internal exposures must be confirmed through analysis of test

plantings. **
In its assessment of dose reductions that mipght be possible due to
removal of contaminated soil, the Task Group posed the followinse questions:

“Given the dose estimates of Tables 1-4, and the dese reductions that can
be expected due to modifications of the diet, can equivalent dose reductions
be achieved by removal of soil and, if so, what volume of soil would have tc
be removed from contaminated islands"?

In order to address this question

*A detailed description of the calculations leading to the estimates in Tables
3 and 4 is given in Appendix IV.
**The Task Group does not favor soil removal as a dependable or feasible
exposure reduction action.

However, such action is reviewed in the Task Groups

considered.
