Processing techniques. The 50-year dose commitment resulting from chronic inhalation of air containing 1.7 fCi m7? of Pu (Table 1} would be approximatel 80 and 2 mrem yr7! to bone and whole body respectively. Calculated cose from * inhalation would be a factor of 200 greater than that from ingestion of proces contaminated food. Dose from inhalation would exceed the proposed limits for ned a uranium fuel cycle (25 mrem, USEPA, 1975): consequent ly human occupancy of the contaminated area would not be permitted.

Eyman. 1976, "Biological Pathways and Chemical Behavior of Plutonium and Other Actinides In the Environment." Jn: A. M. Friedman, Ed. As a result of chronic low-level release of Pu to the atmosphere at Savannah River, direct deposition of Pu on vegetation is the most important pathway of contaminating vegetation. By comparison, Pu uptake by roots from contaminated soil is the major pathway at an Oak Ridge site. The direct deposition pathway leads to higher Pu concentration in vegetation. Calculated doges to humans consuming contaminated vegetation are less than those estimated from natural sources and do not exceed proposed limits. 47-80.
