(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 (11) ~ 0.13 Rem/yr - 0.15 Rem/yr 2,2 Rem 11.5 Rem In contrast, unrestricted living on JANET would result in the following radiation doses: Maximum whole body dose Maximumbone marrow dose Estimated 30-year dose gonads bone - 0.76 Rem/yr - 1,1 Rem/yr - 14 Rem 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 production locations, although undesirable, is absolutely necessary if radiation doses are tc be reduced to acceptable levels. DNA has recommended that a risk-benefit study should serve as a basis for the decision on dose criteria. The Task Group did consicer estimates of risks associated with radiation criteria derived from FRC guidance. Because of many uncertainties associated with predictions of effects of long-term low level doses from Peng ot chet tee DOE ARCHIVES
