(10) The above restrictions result in the following calculated radiation doses: Maximum whole body dose Maximum bone marrow dose Estimated 30-year dose gonads bone ~- 0.13 Rem/yr 0.15 Rem/yr - 2.2 Rem 11.5 Rem ¥ (11) Incontrast, unrestricted living on JANET would result in the following radiatron doses: Maximum whole body dose - 0.76 Rem/yr - 14 Rem Maximum bone marrow dose Estimated 30-year dose - gonads, bone 1,1 Rem/yr 135 Rem Staff recommendations were derived following consideration of various options for reduction of radiation dose below the criteria including modification of the diet, plowing and removal and replacement of layers of contaminated soil. Associated ecological damage and soil disposal problems are unavoidable consequences of large scale decontamination actions. The Task Group did not view partial soil removal as an effective and dependable method of reducing radiation doses, Consideration of restrictions on food oroduction locations, although undesirabic, is absolutely necessary if radiation doses aret. be reduced to acceptable levels, DNA nas recummended that a risk-benefit study shouid serve 15 42 basis for the decisioaca dose criteria. The Task Group did consic wu: estimates of risks associated with radiation criteria derived from FRC guidance. Because of many uncertainties associated with predictions of effects of long-term iow level doses from
