抄録

Contamination of radioactive nuclides on metallic copper surface was studied using oxygen free sulfaric acid solution containing fission products. Experiments for the influences of varions factors such as acidity of the solutions, co-existence of heavy metal ions and cation surface-active agents, and various treatments of copper surface were carried out. The radioactive contamination of metallic copper surface in non-corrosive solution was generally less than that in corrosive solution, and copper surface was contaminated selectively by some radioactive nuclides. The radioactive contamination of copper surface was extreamly decreased by additition of heavy metal ions (Fe3+, Cr3+) or cation surface-active agent into the solutions, and was also influenced by the condition of copper metal surface.
