The new LLL « arithmene was reviewed by the Bair Committee and wasthe basis sssessmerendations of revised ltevels for agricultural and visitat (nev enering islands.?4 The arithmetic error was not discovered | food-ea new guidelines were issued. The new guidelines were base: after ne doses from time spent in various activities, such as | ee or residence, on various islands with different levels serination (Figure 6-15). von. mode! for the LLL dose assessment and Bair Comm rns mendations assumed that the people spent 60 percent oftheir ( eeidential islands, 20 percent on agriculture islands, and 5 percen on ‘. athering islands.It also assumed that 65 percentof the coconuts We fhe other food consumed would be grown on residenceislands. al ated 25 percent of the coconuts consumed would come f eT culture islands and 10 percent from food-gathering islands. ‘The cleanup guidelines proposed removalof concentrations excee 40. 80. or 160 pCi/g as appropriate. The resultant island avera nowever, would be lower. Dose calculations based on these guidel were estimated at 10.3 millirad per year from inhalation and 2.7 millirad vear from terrestrial sources fora total of 13 millirad per yearto the bi This exceeded the proposed EPA guideline of 3 tmillirad per y however,it was well within the International Commission on Radiolo; Protection dose limit to bone which was equivalent to 30 millirad per y COMMITTEE RECOMMENDATIONS® TRANSURANIUM ELEMENTSIN SOIL PRIORITY** ISLAND TYPE SOIL CONCENTRATION*** AREA ' VILLAGE ISLANDS < 40 pCi/g 1/4 HECTARE " AGRICULTURAL ISLANDS < 80 pCi/g V2 HECTARE tl PICNIC ISLANOS < 160 pCi/g V2 HECTARE * HEAVILY QUALIFIEO DUE TO UNCERTAINTIES.
