Transport of plutonium, americium, and curium from soils into plants by root uptake

摘要: Calculation of the dose burden resulting from ingestion food derived plants requires a knowledge soil-to-plant transfer factors for radionuclides interest. A literature search was performed so that magnitude (concentration ratio) plutonium, americium, and curium could be evaluated. The yielded 10/sup -9/ to -3/ plutonium -6/ 1 americium. Hardly any data on were found in literature. are dependent cationic exchange capacity soil, amount organic material pH, type contamination. Complexing agents increase by up factor 1300. Fertilizers exert an influence as species age plants. However, most cases, these relationships have not been studied sufficiently; consequently, time being, there is no satisfactory explanation great variation factors.
