Summary A procedure for counting p32 in plant tissues is presented. The method, based on the use of Cerenkov radiation, involves practically no sample preparation. Plant tissue are placed into vials containing water or hexane and counted with a liquid scintillation counter. Counts obtained, using this procedure were found to be linearily related to that obtained with a G.M. tube. The counting efficiency was, however, higher with the proposed method. The use of hexane is advantageous if leakage of p32 from the tissue is possible, or when higher counting efficiency is desireable. The use of different liquids may also enable a discriminative count of different beta emitters. As suggested recently8 use of wavelength shifter may further increase efficiency of counting Cerenkov radiation.
