We present double-tracer autoradiography with <SUP>35</SUP>S and <SUP>32</SUP>P using imaging plates and an aluminum plate to visualize the individual distribution of sulfur and phosphorus in Brassica napus L.. Because of the different attenuation efficiencies of β-rays emitted from <SUP>35</SUP>S and <SUP>32</SUP>P, the specific image of <SUP>32</SUP>P was taken when an aluminum plate was placed between the sample and the imaging plate. The specific image of <SUP>35</SUP>S was obtained by subtracting the <SUP>32</SUP>P image from the <SUP>35</SUP>S and <SUP>32</SUP>P image. It was observed that high amount of <SUP>35</SUP>S was distributed at the edge of the leaves and in root tips. The <SUP>32</SUP>P was distributed throughout the whole plant and it was found that the phosphorous amount was higher at the shoot apical meristems than those in leaves.
