We carried out a plant uptake and translocation experiment in which a wheat crop was grown on Yolo soil contaminated with /sup 237/Np, /sup 238/Pu, /sup 239/ /sup 240/Pu, /sup 241/Am, and /sup 244/Cm. Studying pot-to-pot variability, we found the data a coefficient of variation of 21 percent. About 9 percent of this variability we ascribe to that of radioanalyses of the plant material. Both uptake and translocation of /sup 238/Pu and /sup 239/ /sup 240/Pu were found to be identical. Likewise, both uptake and translocation of /sup 241/Am and /sup 244/Cm were identical. The Pu concentration was about 10/sup 3/ lower in the grain than in the bottom one-half of the stem plus leaves.
