抄録

The analytical method for radioactive nuclides which contaminate the metal surface was studied. The test specimens were dipped into nitrate solution of the fission products adjusted to pH of 1.4. The radioactive nuclides were removed from the surface by electrolyzing the sample as the anode. 95Zr, 95Nb and 90Y were co-precipitated with the hydroxide of the metals and separated as zirconium phosphate, niobic acid and yttrium oxalate. 106Ru-106Rh were precipitated as sulfides from the filtrate, 90Sr was determined as its oxalate and 137Cs as its perchlorate. From the experimental results, it was supposed that the radioactive contamination with fission products was due to the surface adsorption of radioactive nuclides.
