Attempt to reduce 239Pu and 241Am uptake by wheat plantlets by application of inorganic fertilizers

Inorganic fertilizers are applied to reduce plant uptake of anthropogenic radionuclides, but scarce data are available for 239 Pu and 241 Am. Wheat plantlets were grown in laboratory on limited amount of soil with 239 Pu, 241 Am and different application rates of NPK and diammonium phosphate (DAP)....

Summary:Inorganic fertilizers are applied to reduce plant uptake of anthropogenic radionuclides, but scarce data are available for 239 Pu and 241 Am. Wheat plantlets were grown in laboratory on limited amount of soil with 239 Pu, 241 Am and different application rates of NPK and diammonium phosphate (DAP). As rates increased, the uptake of 239 Pu and 241 Am to the whole plantlet also increased. It was higher for DAP than for NPK, (higher supply of P 2 O 5 and NH 4 + ). Root content was higher than shoots for all experiences, suggesting low mobility within the plantlet. Root content increased with fertilizer rate, but practically no effect in shoots.
