Inorganic fertilizers are applied to reduce plant uptake of anthropogenic radionuclides, but scarce data are available for 239Pu and 241Am. Wheat plantlets were grown in laboratory on limited amount of soil with 239Pu, 241Am and different application rates of NPK and diammonium phosphate (DAP). As rates increased, the uptake of 239Pu and 241Am to the whole plantlet also increased. It was higher for DAP than for NPK, (higher supply of Pub>2ub>Oub>5ub> and NHub>4ub>+). 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.
